How do I grocery shop/make meals for a vegetarian/non-veg family on a budget?

my best advice is to skip the meat completely. it is unnecessary unless you want to feed your family growth hormones, steroids, and antibiotics as part of their diet. children shouldn’t be exposed to those things, and the antibiotics in commercial livestock make those antibiotics less effective, which makes MY family (and your family) less safe.

if your husband is intent on eating meat, send him out into the woods to capture and kill his own dinner. at least that way, his dietary choices won’t be adding unhealthy chemicals into his body, or polluting our planet, or rendering medical treatments ineffective for the rest of us.

Rice is cheap and goes a long way, also lentils can be prepared many different ways and are cheap and healthy. Potatoes are also cheap and filling. Bananas have lots of energy and are also very cheap.
Try your local farmers market for cheap fruits and veggies.

Also at my grocery store they have these vegetarian meal-in-a-box, from Fantastic World Foods, they have stuff like veggie burgers, and veggie taco meat, vegetarian chili, couscous, hummus, falafel etc, they are delicious, they only cost about 2 dollars and they make a lot of food, and they are quick and easy to prepare.

As for cooking in the interest of both vegetarians and non vegetarians, some foods that might work well for you could be: pasta… you could make tomato sauce with ground beef on the side that the meat eaters in your family could add to the pasta later to make Ragu’, or you could make pasta alfredo with broccoli and have chicken for the others to add to the pasta.
Tacos or burritos are another food that would be good for everyone, you could have rice, beans, lettuce, tomatoes, bell peppers, onions, jalapenos, cheese, beef/chicken, and just have it all out and everyone makes their own with what they want in it.
Also, buy eggroll wrappers at the grocery store and make your own eggrolls super cheap, just stuff yours with cabbage, carrots, sprouts or other veggies, and add chicken or pork to some for the rest of the family, you can make a bunch and then freeze them (before you fry them) also, I’ve found that if you are creative you can make a lot more than just eggrolls with the wrappers, I like to make my own jalapeno poppers or pizza bites in them too

I am not a vegetarian, but I eat lots of meatless meals for the budget’s sake. Well, I did, until I got pregnant and started wanting meat all the time, but I know how to accommodate a meat eater with even the meatless meals.

One simple meal for us is tacos/burritos. Meat stays separate, and you use what you want.

We also eat veggie burgers. My husband actually likes potato sandwiches (he learned that while living in Australia) so we make up latkes and bean burgers. Bean burgers freeze well, so it is easy to pull out your own while cooking up the meat for the others.

I have also made some really good ethnic foods that are very low cost. Stir fry is easy, since you can keep the meat separate easily. Fried rice is also good without meat. And of course, if you have ever been to Latin America you know there are a million ways to eat beans and rice.
