One of my favorite comfort foods for winter is lentil soup. It's on our menu at least once a week in the winter.
2-3 cups lentils
1 tsp salt
1 bay leaf
water or homemade or approved chicken stock, enough to cover previous ingredients plus a couple of inches
I just put all of this into a pot, cover with water or chicken stock, and cook for about an hour. Sometimes it goes in the crockpot till dinner, usually it's in the pot. Just make sure it doesn't burn on the bottom. Lentils absorb a lot of water.
Good additions are onions, garlic, spices, sour cream (added at the end), butter, tomatoes, or any other veggies you can think of.
Serve alone, with breadsticks, or with a salad.
