Coat bread slices with cooking spray; place on baking sheets.
Bake at 375 for 10 minutes or until toasted.
While bread bakes, place mushrooms in a food processor, and pulse 10 times or until finely chopped.
Heat 1 teaspoon oil in a large nonstick skillet over medium-high heat.
Add shallots and garlic, and saut 1 minute.
Add mushrooms and salt; cook 18 to 20 minutes or until liquid evaporates, stirring often.
Remove from heat, and stir in remaining 1 tablespoon oil, 2 tablespoons chopped basil, parsley, and pepper. Spoon about 2 1/2 teaspoons mushroom mixture evenly over each crostini.
