Preheat the oven to 400 degrees F. Brush each tart shell with olive oil. Season with salt and pepper. Spread 1-ounce of the roasted garlic puree on the bottom of each shell. Lay 3 slices of the tomatoes and 2 slices of cheese in each shell. Season with salt and pepper. Bake for 8 to 10 minutes or until the cheese starts to bubble and brown.
Spoon the sauce on the bottom of a plate. Place a tart on a plate. Garnish with basil.
