Any moms of vegans out there with helpful hints?

Start with vegetarian times.

There are a lot of ways you can adjust your meals to fit a vegan/vegetarian. If you do a protein and side style of dinner it's very easy to just make two proteins, one vegan and one not. If I'm doing more of a one pot meal, I pull my dd's before I put the meat in and then make sure she has a protein to go with her dish.

I love Isa's vegan cookbooks. They are accessible and don't have 10,000 ingredients per dish, which is what I find is often a roadblock. We're not vegan -- I was a vegetarian for many years, and have had vegan periods, but my husband is the house cook, and neither he nor the kids really want to give up meat or dairy (I don't care about it enough to cook, so that tells you my level of commitment). We do try to have a few vegan and vegetarian dinners every week, however, and the number of great vegan cookbooks out there is surprising.

Even if you don't want to invest in vegan cookbooks, one thing that I think is really helpful is to page through a few at the bookstore and see what kinds of ingredients a lot of the dishes involve, and lay in some of those things as staples. For example, at least in our house, we probably wouldn't keep around bags of cashews if we weren't cooking vegan semi-regularly. It's kind of overwhelming if you have to buy everything specific for each dish when you go to the grocery -- if you have a sense of what ingredients you (he) might need regularly, and can put a bunch in the pantry, that makes it less of a chore to cook.

I'm vegan and my husband isn't. I often eat the 'same' meals I cook for him, just altering it to make it vegan for me. For example, I made taco salad for him and his buddies today. I chopped all the veggies and lettuce into the big mixing bowl, and took some out for me, added their meat and cheese to theirs and in my bowl added black beans tossed in a little bit of taco seasoning mix along with my vegan cheese (Dayia cheddar shreds yummy!) and added guacamole.
One of our favorite meals are small homemade pizzas. I make his with his ham, pepperoni, etc. and pile mine up with tons of veggies, garbanzo beans and the Daiya mozzarella shreds.
When I make chili for him I take a bunch out of the pot for me before adding his meat.
Ask your son what he would like and have him help out in the kitchen if you dislike making separate meals.
Since its summer, fresh veggies are more available and tasty. I'm on a corn on the cob kick right now as well as lots of yummy salads, with different veggies every day.
I also like cooking up some cous cous or quinoa and chopping lots of veggies into it. Sometimes I add a little fat free Italian dressing to it, like I do with pasta salad.
You can google up TONS of vegan recipes online too!
Here's one I found recently and love:
www.forksoverknives.com/recipes/black-eyed-peas/
I subbed great northern and garbanzo beans for the black-eyed peas, omitted the maple syrup because I don't like it, left out the sage and added a squirt of bbq sauce to the kettle. It was so delicious that I made two batches in a week!
