|The Mark Burger|
He said he likes to use pork burger (but I used 92% lean beef) and mix in diced onions, A1 steak sauce, and mustard (I used dijon mustard). I didn't measure, but put in about how much I thought might be good. The obvious next steps were to make patties and grill them - I made four 1/4 lb. patties.
The other twist was that, instead of ketchup, he said he tops with BBQ sauce, so I used Sweet Baby Rays BBQ sauce. I also bought a jar of pickles that also had pickled red peppers and carrots in the jar and used a mix of pickles, red peppers, and carrots on top.
And, to make a long story short, it was delicious - I'll likely make The Mark Burger again this grilling season and recommend you try it, as well. :)
