This is what I have for dinner almost every day because it's the healthiest and least expensive recipe I can think of. It serves two.
Bring 3/4 cup brown rice (uncooked) to boil in 3 X as much filtered water. Add sea salt to taste, and lime leaf and/or your favorite whole spices (ground ones might be better added near the end, since they tend to get stuck on the inside of the lid once they've been boiling for a while), one diced potato, jalepeno peppers, any other vegetables. Add the vegetables according to how long they normally take to cook (so, root vegetables before leaf).
In a shallow (cast iron, if possible) pan, stir fry an onion until it's translucent, and remove from heat immediately. Keep separate and add at the end if you like your onions with all the flavor intact and on the crunchy side, or add earlier if you like the flavor to permeate the whole dish thoroughly.
When the rice is cooked, turn off the heat and keep the lid on until almost all the water is absorbed. Add some minced garlic. (I like it not too well-cooked; that's why I add it last. Some prefer it cooked separately in olive oil with the onions, and added at the beginning.)
When the rice has absorbed all the water it can (which will not be all of it if you used the 3:1 water:rice ratio) add:
1 tbs. coconut oil
some canned tomatos
dash of your favorite vinegar, and/or lime or lemon juice
some tahini
(I like about a teaspoon of black and/or cayenne pepper, or some kind of masala mix.)
Sometimes I add some frozen peas at this point. I like them very slightly cooked, and this way, they cool it down nicely. This helps if you don't have a/c!
It will be the consistency of mac and cheese, but way healthier! If this consistency doesn't appeal to you, add less water at the beginning. (I find the smoother consistency easier to mix at the end, and the tahini really thickens it, that's why I use more water than usual.)
This can be made with corn meal for polenta, or any other type of grain. Flaked grains are great because they cook in almost no time.
The grain with the tahini makes a complete protein, I believe.
