Preheat oven to 400 F. Lay sliced baguette on a cookie sheet. Drizzle all over with olive oil and a sprinkle of salt and pepper. Flip and drizzle on more oil.
Place in oven and toast for about 4-5 minutes watching closely as they start to turn golden brown. Turn them over and give them one more minute. Remove from oven and place toasts on serving platter or board.
On each piece, evenly smear on ricotta cheese. Carefully layer on prosciutto, some arugula and finish with cantaloupe.
Just before serving drizzle each piece of toast with olive oil & some cracked black pepper. Serve immediately.
If using glaze, drizzle on just before serving.
