"Create a one-gallon crockpot comfort-food stew suitable for a Russian Orthodox Church coffee hour during the Nativity Fast. It should be meatless and appropriate for fasting, but still hearty and satisfying for a chilly November afternoon. Use a substitute for chicken or beef such as mushrooms, beans, lentils, or a combination. Aim for a warm, comforting flavor profile similar to a traditional stew, and scale the recipe to yield about 1 gallon total. Include imperial measurements only."
