Yes, you don't need yeast to do tortillas- just flour, water, and sometimes baking soda (depending on the recipe you use). Allrecipes has some good ones. I just use flour and water

. It takes a bit of time, but if you do a bunch of tortillas in one sitting you can freeze them and have them for a while
Glad you enjoyed the curry! Yes I usually add generous amounts of peanut butter. I usually make mine with coconut milk, peanut butter, red chili paste (Thai Kitchen has some versions you can find at many grocery stores), ginger, lemon grass, and lime juice. But you can tweak as you like. (Note: this is very similar to what I do:

You can also do curry paste + coconut milk for a delicious curry, if you get tired of peanut butter. It's lower in fat, calories, and sugar.
Pad thai and drunken noodles are other similar dishes you can cook with similar ingredients. I do a very light drunken noodles- basically just sautee your protein (chicken, tofu, etc) and bell peppers and tomatoes in soy sauce, ginger, garlic, and just a bit of brown sugar. Then toss in rice noodles into the mix and cook until noodles are coated and mixed with other ingredients.
I know several of the items I mentioned are not on your normal grocery list, but things like soy sauce, ginger, and garlic are inexpensive and last a looong time.
I've found Thai, Indian, and Mexican food to have some great inspirations for new things to do with the same "old" products. It's all about the spices, which fortunately, are calorie-free
