I love these burgers. They are packed with so much flavor. I started making these last summer and the kids ask for them a lot. I used ground sirloin and found that it was really juicy. When I make these burgers, I put a slice of tomato on top while they are still on the grill and melt garlic cheddar over the tomato, WOW! Sometimes I even shred the cheese and ix it in as well.
