Cut a ½ inch slice off the top and bottom of the tomato (store the center of the tomato for a later use). Cut the woody stem area off the top of the tomato. Drizzle the cut sides of the tomato with a nice extra virgin olive oil and season with coarse sea salt and fresh ground pepper. Set to the side.
Form the patties out of the Italian Sausage. Make them just a little larger than your tomatoes. Heat a CLEAN, OILED grill to 350 degrees, keeping the middle burner turned off. We want to cook the burgers over the indirect heat of the grill. Cook covered for approximately 8 minutes on the first side and 6 minutes on the second (timing may vary depending on the thickness of your burger). The burger should reach an internal temperature of 165-170 degrees.
