I typically make 1-1/2 of this recipe. Six cups of milk and two 12ish oz. cans of tomatoes usually fills my regular sized crock pot.
1/2 lb. hamburger, browned
1/3 c. chopped onion
1/3 c. chopped green pepper
1/2 c. flour (white or wheat)
4 c. milk
1 - 16 oz. can tomatoes (whole, diced, or whatever is your preference)
4 cubes or 4 tsp. beef bouillon
1 c. shredded cheddar cheese
Put browned hamburger, chopped onion, & chopped green pepper into crock pot. Stir in flour. Gradually stir in milk. Add the tomotoes and bouillon.
Cook on low for several hours or high for a few. Whatever you have time for! Stir occasionally.
Before serving, stir in shredded cheese.
