Variation on Will's Bread

OK, so while we were wine tasting, one of the chef's at Tobin James brought out some YUMMY treats. While I was three sheets (or more) to the wind, Will remembered some of what the delectable treats tasted like.... Here's my version of his version:

I usually make two types of bread, one geared more toward adults, and one for the kiddos... so for the "kid" half, I just left off the tomatoes & green onions. The white onions with the brown sugar taste sweet, so they didn't even notice they were there.

Dice up a couple fresh roma tomatoes, (5 or so) green onions, and sprinkle some (1/2 cup +/-) balsamic vinegar on them while preparing the rest of the recipe
Fresh loaf of french bread, cut in half lengthwise
Light Mayo & shredded parmesan cheese mixed, about 4:1 ratio, spread onto both halves of the bread
Saute approx. 1/2 cup of white onions and 2 cloves of garlic in approx. 1 Tbsp of olive oil, until onions are translucent, but not brown
Spread that on both halves of bread
Sprinkle brown sugar over the onion mixture
Sprinkle tomatoes & onions over the onion
Salt & pepper to taste
Sprinkle a little more parmesan, romano or feta cheese over the top

Broil in oven until slightly brown and a little crisp.
