nice open-faced sandwich recipe from the Moosewood cookbook:

Broccoli and Friends
Dice broccoli and onions finely and saute in butter with some salt, pepper, basil and thyme. Cook until broccoli is bright green and onions are translucent. Place on a slice of hearty bread (fresh baked sourdough is nice) and top with grated cheddar cheese, then broil until melted and bubbly. Make at least two.

I guess you could put meat in this but it's very nice as is.
