Heat a heavy skillet over medium high heat and add 2 teaspoons of olive oil. Place one slice of bread in the pan about 3 to 4 minutes until toasty golden on both sides. Repeat the toasting batches as necessary. Set aside.
Saute the peppers, onions, garlic, salt, pepper and snow crab meat in 2 tablespoons olive oil over medium heat until peppers are soft &mdash about 5 minutes.
Place crab mixture on top of each bread slice. Top each slice with Provolone cheese. Bake the sandwiches in the oven for 6 to 7 minutes, until cheese is melted. For toasty, tops, sprinkle sandwiches with bread crumbs and broil for another minute.
