Broccoli Cheese Buffs

2 bunches broccoli (about 3 lbs)
2 egg whites, at room temperature
1/4 tsp salt
1/2 cups shredded Swiss cheese
1/2 cup mayonnaise

Trim tough ends off broccoli, then cut into spears.
Bring a large pot of salted water to a boil, then set broccoli in and cook for 3 to 5 minutes or until just fork tender; drain.
Arrange cooked broccoli in a shallow broiler-proof baking pan.
Put the egg whites and salt into a mixing bowl and beat (with electric mixer) until stiff peaks form.
In separate bowl, mix together the cheese and mayonnaise.
Then, with rubber spatula, gently fold in cheese/mayonnaise mix, being careful not to 'deflate' the egg whites.  Don't be too concerned about getting the mixture evenly blended - some globs of cheese/mayonnaise are okay.
Spoon this mixture evenly over the broccoli in baking pan.
Set rack in oven so baking dish will be 6 inches from broiler element.
Turn oven on BROIL on highest heat.
When broiler is preheated, set baking pan in oven and broil for 4 to 5 minutes or until cheese/mayonnaise turns golden brown.
Remove and serve hot.
Will serve 4 to 6.
