French Onion Crostinis - onions

Method

• Peel onions and chop in half.
• Lay each half of the onion flat side down and slice onion in 1/4 slices.
• Separate layers of the slices so you end up with about 6 cups of half-moon shaped pieces from 3 medium size onions.
• Heat butter in a large frying pan until melted and add onions.
• Saute for 5-10 minutes until onions begin to soften.
• Add salt, pepper, vinegar, and Worcestershire sauce and place heat on medium.
• Cook onions for another 30 minutes or so, stirring often, until onions are very soft and cooked through.
• While onions are cooking, preheat oven to 375 degrees F and line 2 cookie sheets with parchment paper.
• While onions are cooking, slice baguette on the bias in slices a little less than 1/2 thick.
• Spread one side of each piece of baguette with a thin layer of mustard and place on the cookie sheets, mustard-side up, fitting as many onto each pan as you can.
• Once onions have caramelized, place some onions on top of each piece of baguette, enough to include onion in each bite.
• You can add more or less to taste, depending on how many onions you chopped.
• Sprinkle a tablespoon or two of grated cheese on top of the onions on each piece.
• Bake crostinis in the oven for 15-20 minutes or until cheese has melted and begun to bubble.
• You can also finish with a minute or two under the broiler, but keep a close eye on them to make sure they dont burn.
• Serve warm!
