Start with an empty freezer because you haven't been to Costco in a month and you're not going again until tomorrow.
Open your cupboard, see the jar of lentils, and remember that you actually like bolognese sauce with lentils better than with meat anyway.
Do a jig, being careful not to knock anything over in your pocket-sized kitchen.
Throw one cup of dried lentils in a pot with 2.5 cups of water, 1/2 t. salt, 1 bay leaf broken in half, and one bouillon cube. Simmer for about 20 minutes - I like mine with a bit of bite to them, so I don't cook the smithereens out of 'em. (Basic lentil recipe from More with Less calls for 1 t. salt, though I add less when I'm adding them to an already salty-ish sauce recipe. If I'm making soup with them, I'll go ahead and use the full teaspoon.)
Drain the lentils and chuck them in with your favorite homemade or storebought bolognese sauce, and serve over pasta, couscous, or polenta.
