Another ditto to the "mayo on the outside" part. We learned this trick back in the 70's when Hellmann's Mayonnaise had a commercial of a nice typical american family on a cold night making tomato soup & grilled cheese. The mom did the mayo trick, so the next time my mom maid GC & TS, she did it too. It's great!
