Cheeseburger Tomatoes

1 tbsp Extra Virgin Olive Oil
1 cup, chopped Onions, raw
2 clove Garlic
16 oz 90/10 Ground Beef Sirloin
1 tbsp Ketchup, Heinz
3 tsp Frenchs Yellow Mustard
4 medium whole (2-3/5" dia) Red Ripe Tomatoes
4 serving Morton Coarse Kosher Salt (1 serving = .25 tsp / 1.2g) (by NEZALHUALIXTLAN)
.5 tsp Pepper, black
.66 cup Kraft Finely Shredded Sharp Cheddar Cheese
.5 cup Fresh Express Shredded Iceberg Lettuce
4 oz Vlasic Zesty Dills (1/2 pickle)
1 tbsp Sesame Seeds

In a medium skillet over medium heat, heat oil. Add onion and cook until tender, about 5 minutes, then stir in garlic. Add ground beef, breaking up the meat with a wooden spoon, and cook until the beef is no longer pink, about 6 minutes. Drain fat. Season with salt and pepper, then stir in ketchup and mustard.
Flip tomatoes so they are stem-side down. Cut the tomatoes into six wedges, being careful to not cut completely through the tomato. Carefully spread open the wedges. Divide cooked ground beef evenly among the tomatoes, then top each with cheese and lettuce.
Garnish with pickle coins and sesame seeds.
