Corn and beans, 3 ingredients. 1 cup dried beans (around 50 cents), 1 can of TJ cut corn (89 cents), 1.5 cups water. Pressure cook the beans and water for 30 minutes. Release pressure or wait for it to drop by itself depending on how impatient you are. Stir in the corn.
Before you stirred in the corn, the just-cooked beans were boiling hot, but since the corn was at room temperature, the whole mix now is nice and warm but not scalding, so you can eat it right away. Nourishing (natural protein combination), low sodium, vegan, tasty, cheap, hard to beat.
Sometimes some pasta sauce if I have some. I had a bag of tomato powder a while back and used that, but it wasn't so great. A 6 oz can of tomato paste works pretty well except it feels stupid to open the little tiny can and spoon the paste out.
