I think we had this when we were at Aunt Rene’s for Thanksgiving one year. Neither Mom nor I actually remember eating it, but the recipe card says “Excellent” so hopefully it is. Note from Mom: I made it and it is really good!
Pour green beans into greased 9x13” pan. Sprinkle with onions. Combine sour cream & soup in a bowl and distribute spoonfuls on top of onions. Cover with tater tots & sprinkle with shredded cheese. Pour melted margarine on top. Bake for 1 hour at 350 degrees.
