Don't give up!! Keep trying new recipes until you find some that you all like. Think about what you enjoyed eating before this WOE and find some similar things to try. Post here some things you would like to try -- lots of folks here have been where you are and can help. As you get the hang of this, I think you will find your grocery bill goes down ...at least mine did.
Some things that I find work for me:
I cook dried beans on the weekend and make enough so I have some to eat in different ways all week -- what I call the "bean of the week." Dry beans are dirt cheap -- I buy mine at an Amish grocer, but even at the regular grocery store, they are cheap, cheap, cheap.
Soup - my basic recipe -- simmer a diced onion and some sliced carrots in 2-3 cups water until tender. Add 2-3 cans diced tomatoes, the bean of the week, a bag of mixed veggies and some flavoring -- garlic, chili powder, etc. Adjust the proportions til it looks right and tastes good. One night, reheat it with some pasta in it, one night, add potatoes, one night, serve over rice -- I tend to take it to work for lunch, too.
Mary McDougall's corn and bean enchiladas -- these are super good!
Pasta and broccoli -- cook some pasta and just before it is done, throw some cut up fresh broccoli into the pasta pot and let it simmer til the broccoli is done. Drain and eat!
Rice and a bag of frozen veggies.
Oven roasted potatoes -- cut up some potatoes, put them on parchment paper on a cookie sheet, stick them in the oven at about 375 for about 45 minutes (or until they are brown). These are great with some frozen veggies for dinner and put the leftovers in the fridge to snack on.
Veggie burgers -- I asked for help with this on this forum and got some great ideas. Do a search here and you will find some great recipes. Jeff Novick has a good basic recipe to start with.
corn tortillas -- I just tried this this week. Get some corn tortillas (read the label) at the grocery store -- cut into fourths, put on parchment paper in the microwave -- about 3 minutes and you have delicious corn chips - yummy!
Hang in there -- there is hope!
