1. Finely dice the tomatoes, red onion, and cantaloupe. Depending on size of your fruit and onion, you will want to end up with equal parts cantaloupe to tomatoes, and red onion should be half the amount of tomatoes you are putting in. Place in a mixing bowl.
2. Cut the basil leaves into ribbons, and add to mixing bowl. Add the white vinegar to the mix, and stir to combine. Season with salt and pepper and set aside.
3. Slice the baguette into 1/2 thick slices, 8 pieces. The bread can be toasted in a toaster, grilled on the grill, or toasted in the oven. Grill or toast bread to get bread crispy but not too dark. Once bread is toasted, brush grapeseed oil on the slices of bread.
4. Top the bruschetta bread slices with the topping that was set aside and enjoy!
