The longer I'm veg'n the more foods I seem to eat!
I'm really frugal on food too, I've let up recently, but still make some really cheap dishes.
It seems once I started to see all food vegetarian I could just cancel the meat and switch to beans, lentils, nuts---whatever seemed the right fit.
It's easy to sub chickpeas, mushrooms and beans, lentils both red (mushy) and green or brown (hold their shape), tofu is my favorite, tempeh
I swear- try this recipe for tempeh sausage--
Soups can all be made veg'n
Casseroles can all be made veg'n.
In the early days I remember how foods just felt - lacking- esp when I gave up dairy. After some time I found myself using what others think of as weird combinations, but are incredible
Nutritional yeast and Braggs amino acids
Cumin tasting foods with dill pickles
Just topping grains and veggies with peanuts
Playing around with sauces
