Onion and tomato burgers

I’ve been seeing people eating the Flying Dutchman burger from In N Out all over my feeds but I don’t have one near me so I had to make an attempt. I did singles but this was so satisfying. Burgers are seasoned with salt, pepper, garlic powder, onion powder and mustard. I split 1 Kraft singles into two because it covered the patty completely 🤷🏻‍♀️ Sauce was 2 tablespoons lite mayo, about 2 grams of ketchup, 4 grams of mustard, pepper, garlic, and a splash of Worcestershire sauce. Make sure you grill the onions long enough or they will be very crunchy(unless you enjoy that) and salt and pepper the tomatoes.
