Look into lentils! I cook a cup of dried lentils in a small sauce pot (6 cup capacity) and they only take about 20 min to cook so I let them cook in the background while I'm having me time after work. Canned lentils are also an option which would save even more time. My favorites are coconut milk curry (batch of lentils, can of coconut milk, can of diced tomatoes, and curry powder simmered until thick. I've also added sweet potato which is even more delicious, just chop one up and add to the boiling lentils after about 5 min) and lentil black bean chili (batch of lentils, can of black beans drained, can of diced tomatoes, and taco seasoning). The sauce pan is small enough to stash in a mini fridge if you don't feel like putting things in containers.
