My older sister shared this recipe with me when I first told her I joined my church's freezer meal ministry. She suggested this meal since it was easy, inexpensive, and something I could make for myself (I'm a vegetarian) in addition for others. This meal has been requested by those who've had it before, vouching for its tastiness. This recipe is super easy to prepare: just chop the onion, mix ingredients, bake, cool, and freeze. That's it. It's healthy, gluten free, dairy free, and vegetarian. The lentils add some protein punch. Use any type of rice you prefer. I use basmati. Note: you don't need to cook the rice or lentils before making and baking the casserole.
