A simple dish combining leftover canned lentils, leftover cooked brown rice, asparagus steamed in the microwave (2 minutes), tossed with a couple tablespoons of Bel Soy, a dash of sodium-reduced tamari, and nutritional yeast flakes. Total time: about 5 minutes. Price tag? Under $1 I would guess.
It really helps to make extra rice, noodles, legumes, and so forth that can be quickly combined into last-minute meals.
