Slice rolls in half, length wise. Brush the inside of each half with olive oil (set aside remaining olive oil).
Place in a skillet on medium heat, oil side down, until toasted for about 3-4 minutes. Remove from heat.
Spread pesto evenly on each half of the roll.
To build the sub: Start with the roasted tomatoes; enough to cover the roll.
Next add a slice of cheese, followed by 1 slice of each meat. Place the top of the roll on.
Put on a non-stick baking pan. Brush tops of sub rolls with olive oil and a sprinkle of parmesan cheese. Lightly cover with aluminum foil.
Bake in oven at 350 degrees F for about 15-20 minutes.*Chef’s note: You could also add a slice of prosciutto!
