L.T.
Some things I make and freeze for later use that you could probably alter to fit your dietary tastes are chili, bbq pulled pork for sandwiches, pot roast, meatloaf, meatballs, spaghetti sauce. I also like to roast beef, turkey and ham then cut them in a vairety of ways for different types of meals For example, I might slice some ham for sandwiches (thin), cut thicker slices for ham steaks and cube some to put in salads.
Do you use a crock pot? I love to be able to just throw the ingredients in the pot in the morning, let it cook all day then serve at dinner time. I make soups, stews, chicken with tomatoes/pepper/onions, bbq meats, roasts. As you can see I don't do a lot of vegetarian cooking, but you could google for recipes if you are interested in that method. Best wishes to you!
