This is the best burger I've ever tasted. Didn't need anything else on the burger. Awesome! I'm going to try other recipes in the LandOLakes website to see if they are good as this one.

This recipe is so simple to do, and the taste is wonderful. The stone-ground mustard works very well, and really compliments the flavors of the carmelized onions. I don't have a grill, so I just did them in a saute` pan. I did add a slice of pepperjack cheese to mine, and I think I now have a replacement for my favorite pattymelt! I made them smaller because of my diet restrictions, and they reheat very well, too. This one is a real winner and will go into my personal cookbook.

    The burger patty itself is just the beginning. Start with chicken, pork, veggies, a portabella mushroom or good, old-fashioned beef. Then heap on the flavors from there, with cheese, onions, salsa and even fruit.
