2c Green lentils + one large onion +.5 to 1 c tomato sauce + some cooking oil or butter + plenty garlic + pepper n salt = delicious side dish.

Takes 20 mins to half hour to cook to softness on the stove. Of course you cover the mixture with water. If you don't have tomato sauce, sub some other veggies for complementary flavour. I buy a big can for $1.40 and freeze 3/4 of it in 3 containers, using the last 1/4 when I open it.

Also, try googling ingredients + recipe and look at the results for easy ones. Or use simple as an additional search term.
