Preheat broiler to high. Slice baguette into 8 (1/2-inch-thick) slices. Place bread in a single layer on a baking sheet. Broil 2 minutes or until browned. Combine basil leaves, mint leaves, peas, olive oil, lemon juice, salt, and garlic in a mini food processor; pulse until smooth. Spread about 1 tablespoon pesto on each bread slice.
