I have a vegan daughter, and the rest of us eat meat.
I want to eat meat about 2 times a week (only chicken - I have issues with cows from an environmental POV). DH and DS would like to eat meat 4 (DH) -7 (DS) times a week. In many ways that is too bad - I cook, so you sort of get what I am making. I certainly have no issues with people cooking themselves some meat if they want to, but they can almost never be bothered.
Here are things we do:
We buy cooked, cut up chicken breast and cooked bacon. It is pricey, so people are mindful of quantity. They add it at the end to stir fry's, salad and pasta.
I substitute milk for soy or almond milk in dishes, as well as water and juice where appropriate. Honest to goodness - people rarely notice.
If you take out the meat in dishes, you might want to substitute it with something - beans, nuts, seeds and soy products are the substitutes (unless you eat eggs and cheese - but really, they are high in cholesterol, so should not be the only or go-to substitutes.
We use nuts and seeds a lot. I put sunflower seeds in stir fry's and caramalised pecans in salads - yum!
I like tofu best cut into strips and fried (presented with a dipping sauce). If you do tofu incorrectly it can really turn people off. Figure out how to use it best.
I rarely use beans - they ellicit groans from my family. Use what works for yours.
There are some "meaty" foods that are meat free - portobello mushrooms make great burgers (as do Boca burgers
). Veggie ground round or TVP can be added to chili's and sauces if you feel the need for extra meaty texture. I think many people move away from fake meat after a while - but if they help your DH, go for it.
