well there's a zillion different kinds of squash, and in my opinion they're not real super tasty, but they filling and good for us.
if there's a trader joe's near you, there's tons of stuff that's not expensive (along with those that are) and you can find all sorts of amazing things to try.

have you tried mesalah's and vindalu's and dal's?
and a quishe is pretty much just an omlet in a pie shell, easy as scrambled eggs to make.

put some canned spinich with some cracker or matzo crumbs or pancake or biscuit flour and break in some eggs and scramble.
but that in an oven proof dish or pie shell and bake, it doen't take long, i don't remember the time,
but when it just starts to brown on the top its probably just right.

there are cook books that have all sorts of neat ideas. food coops, not just book stores, have tons of them.

have you tried string beans (like so called french cut best for this or most anything, you could even start with raw ones or even growing them if you had any dirt to grow them in) with cream of mushroom and those predried onion rings on top for crunch.

i mean it doesn't take fancy things with lots of steps that take hours, there's tons of really simple things.

chop some green onion tops into almost any thing to liven them up a little. but toward then end so they don't get all mooshed.
and a squoze of lemon/lime/concentrate or cut a real one and sqose it in real time, for things like soups and stews.

extends the saline side of flavor while reducing actual sodium needed and plus boosts imune system with that extra bit of 'c'.
of course it doesn't go in everything. nothing milk or dairy based, but in almost everything else.
a light sprits, not enough to taste, unless you aquire a taste for it.

all these are things, i live on the same amount s.s.i. gets, except mine comes from the v.a. so none of what i'm suggesting,
and these are what i do, are going to require massive cash flows.
