Swiss Broccoli Tomato Stacks

I once made 300 of these for a wedding dinner and even 300 take no time at all!

Cut 3 large tomatoes in thick slices. Pat dry and sprinkle with salt and pepper. Set aside 2 TB shredded Swiss cheese from a 4-oz package. Mix the rest of the cheese with a 10-oz box of frozen chopped broccoli, cooked and well drained, and 1/4 c. chopped onion.

Place the tomato slices on a baking sheet, top with the broccoli mixture and with the reserved cheese on top. Bake at 375 for 40 minutes or easier yet, broil 8" from heat  for 10-12 minutes until the cheese bubbles and the tomato slices are hot.
