Do you or would you cook for yourself?

Yes, I cook for myself all the time.
I also take home made meals in to work with me.
I don't cook every single day though, I'm happy to eat the same thing 3 or 4 days in a row, therefore in winter I'll make a soup or pasta sauce etc enough for several days at a time.

I live alone and cook for myself. Usually I make up a couple of larger meals on the weekend and just eat the leftovers for lunches and dinners throughout the week. Keeps it simple.

I would cook for myself. It wouldn’t be anything fancy and most likely I would make multiple portions so I’d have leftovers and not have to cook every night.

I am too cheap and picky and allergy ridden to eat out all the time. Also, I get home at 4:30 and I am not leaving the house to get dinner when I am actually hungry. Generally once I am home, I am home for the evening, and I am not old enough to eat at 4:30.

When my husband is out of time I make or Costco a rotisserie chicken and use it to make simple meals, so I am cooking somewhat, but probably not as elaborate or varied as when my husband is home. Wraps, soups, simple pastas.

I too am happy eating the same thing several meals in a row, so I would probably just cook like he was home and just eat it for 2 days in a row (we take leftovers for lunch everyday).

I am absolutely much less motivated to cook for myself, but I do it anyway.

It is a toss up for me. I go through times I eat out way more than is good for me. Other times I do heavy "snacking" (cheese, fruit, cereal, yogurt type) other times I cook once or twice a week and eat multiple meals from it.

Today I put 4 pound of chicken thighs in the crock pot. Most of them well get frozen but I use one a day to make various chicken dishes like a chicken chili, chicken pot pie in a bowl.

I would cook things that would freeze well and make individual sized dinners. I just got an air fryer on Friday and have happily played with that this weekend.

Same here, except I don’t take lunches to work.  It makes me very happy to have leftovers at home waiting for me. I only cook stuff that I really like and eat it for days. 
I used to cook for the 5 of us forever.  Now that it’s usually just me, I still cook the exact amount that I am used to and eat it til it’s gone.  Although I have frozen some if there is way too much. 

I have no choice as I have a load of allergies so I would have to.

But I would be smart about it and do enough for 2 so I'd have left overs for lunch next day or triple for freezer left over.

I cook for myself a lot. I have to eat, and usually what I’m cooking for others is what I want anyway, just more of it.

Most things don’t really take much time to cook. Pasta is super fast, and there are some amazing raviolis available either in the frozen or refrigerated sections of the store. Make a simple brown butter sauce, or use jarred sauces to go with. A small salad on the side, and it’s a 10 minute meal. Fish is fast, served with veggies & rice, another 10 minute meal. Burgers, chicken, steaks, all quick make a soup one night, eat for several. Most freeze great, and can be pulled out later.

I have never lived alone, but I've often said that if it was just me I would live on sandwiches, soup, eggs, and cheese and crackers.

But in reality I would probably try doing a meal prep day once a week to have food for the rest of the week. I like to cook but I don't like 'having' to do it every day.

DH has so many health issues, that he often just eats soup or cereal.

I do cook for both of us, but if he can't eat it, I eat it for lunch or the next day's dinner. I freeze individual meals for myself, too. I don't want to eat something 3 or 4 times, so freezing works great.

I also order take-out occasionally and freeze portions, so I have meals available.

Yes, I joined a Forks Over Knives meal plan for a year.  Super easy, it plans the meals, grocery list, recipes. Very easy to choose portions & they have left overs planned into their plan. I added one portion so DH can have one meal as a side. 
That said, do you belong to Costco? In the deli section, near the rotisserie chicken, they have packs of shredded chicken breast. The pack is more expensive than 1 rotisserie chicken, but cheaper by the pound & no skin or bones, just white meat. I used to buy those, portion out servings into snack baggies, then throw them in the freezer. If I pulled one out, it was thawed by lunch. I could add them to salad, tacos, just about anything. 
You might also consider planning two or three meals, and have a cooking day to make it all. Dish into containers and stock the fridge. All you would have to do is microwave a container, and ready to eat. 
Take care,
Sharon

I was single until I met DH when I was 36, so yes I did cook for myself. Not as fancy as I cook for DH, but enough to sustain me. I also had a grocery store near my place that sold stuff I would never make like Crawfish Pie. OMG! It was to die for and it was individual portions so perfect for me.
