1 tbsp. 

 mustard

slicing tomatoes

 salt and pepper to taste

2/3 c.

1. In a medium skillet over medium heat, heat oil. Add onion and cook until tender, about 5 minutes, then stir in garlic. Add hamburger, breaking up the meat with a wooden spoon, and cook until the beef is no longer pink. Drain fat. Season with salt and pepper, then stir in ketchup and mustard. 
2. 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. 
3. Garnish with sliced pickles.
