What's your "go-to" dinner meal?

Grillled marinated chicken, rice and a salad!

It wouldn't be my go to meal if I was taking dinner to someone or having people over, but your last category - a weeknight meal.  In fact, when I'm home it's my go to most nights.  Grilled chicken with some sort of marinade or Mrs. Dash, brown rice, steamed vegetables. I do the chicken and rice on Sundays for about 3 days worth of meals, and just buy the bird's eye frozen steam in a bag vegetables that takes about 3 minutes when I get home from work and lasts me for a couple meals. Divide everything up in Ziploc containers, and voila - lunch and dinner for 3 days ready to go.  

Stir-fried chicken and vegetables with rice.

Some kind of stir fry

We always have the ingredients for spaghetti so that would be my go-to. That or frozen pizza.

Some kind of Mexican- usually tacos, but fajitas, burritos, or enchiladas work too!

pasta salad.... tri-color pasta with chickpeas, tomatoes, hard boiled eggs, avocado, cucumbers, roasted peppers, little onion, some parm or feta cheese, maybe pepperoni, hot peppers, olives, dressing and spices... Sometimes I make it more Italian other times more Mediterranean... Works as a meal, side dish, lunch, etc.

For just the family it's stromboni, which is what we call stromboli. The kids love it and it's easy to make. If we are having guests over DH makes schnitzel with all the sides: potatoes, sauerkraut, red cabbage, steamed vegetables, spatzel. It's a really good meal, but a bear to clean up after.

I hate having to take someone a meal, I never know what will travel well. Last time I did chicken noodle soup with homemade noodles, sliced bakery bread and warm cinnamon rolls. That went over well. And it's easy to do.

I make something similar only I use ground beef and along with the onion and garlic I throw in diced green pepper, mushrooms and sliced pepperoni.  If I feel like getting fancy I sprinkle mozzarella cheese on top and stick in the oven till the cheese melts. 

This is really DH's go to meal when he has to cook.

Homemade Mac and cheese...love it

I actually have a different one for each of your examples.  

To take to a friend (if they have a crockpot) is cheater's pulled pork: a loin of pork, a bottle of BBQ sauce, a package of rolls & a bag of chips.  If I drop it off early enough, they can pop it in for dinner that nite, or they can freeze it easily to eat at another time.  It doesn't require any cooking expertise and it's a little different from the typical baked ziti, macaroni & cheese, etc.
 
If I'm having people over (last minute & I haven't planned anything else), it's pasta w/Knorr sauce - either Parma Rosa or Creamy Pesto.  I never have less than 2 lbs. of dried pasta in my pantry and I order the sauce packets from Amazon, so I've always got at least 5 on hand.

If it's for my family & needs to be quick, it's Market Day's Lasagna Roll-ups topped w/a jar of tomato sauce.  I always have those 2 on hand and it cooks in the microwave really quickly.

Go to meal for company: Marinated salmon, rice, salad, hummus and veggies.

At home during the week : chicken burgers, lentil tacos, pasta or tuna melt.

If we are having company it's a Tri Tip - DH makes a killer tri tip.

Week night meals for us - Trader Joes Orange Chicken, steamed rice and pot stickers. We always have those 3 items in the house.

I was expecting to see a stir-fry recipe This sounds like my go to spaghetti w/meat sauce when I need something fast and usually toss in fresh spinach.

There is always a pack cheese tortellini in our freezer and this makes an even quicker meal. I pull it out of the freezer, boil the water, cook 5-8 minutes drain & toss with sauce (pesto, olive oil, tomato or Alfredo - whatever is easiest and/or in the fridge). While the water is boiling I make a raw veggie plate with whatever is in the fridge (usually baby carrots, red peppers & cucumbers).

My other fast meal is rotisserie chicken, Caesar salad and sourdough bread.

Grilled flank steak, vegetables grilled (onion, zuchini, asparagus, sweet peppers, eggplant, fennel) or roasted (onions, zuchini, carrots, peppers, beets, butternut squash) depending on the time of year and grilled/roasted lemon potatoes would be the go to meal for friends coming over.
