Have you ever had one of those super awesome hors d'oeuvres at a party or wedding and then found yourself wanting that same thing every day for the next month? Well... this is one of those dishes. It's fresh, garlicky, balsamicky, and it's pretty!
Slice the baguette about a 1/4-1/2 inch thick, you'll and get about 26-30 slices. Slice the tomatoes, making sure to get enough for 1 per crostini. Slice the mozzarella cheese about the same size as the tomatoes, maybe a little thinner.
Very thinly slice the onion. Toss them in a warm saucepan with 1 tbsp of margerine, the sugar and salt & pepper to taste. After about 2 minutes of tossing, dump the balsamic vineger in the pot, stir, and cover for another few minutes before stirring again. Repeat until the onions are purple and very soft.
In a small bowl, combine the oil, garlic, parmesan, and seasonings and microwave for about 1 minute. This will infuse the oil. Brush each slice and broil for a couple minutes- until edges are brown.
On each slice, put a tomato, followed by a small piece of basil, then a piece of the mozzarella. Lastly, top with a few of the balsamic onions and shake a small amount of parmesan on the whole platter.
