The Ultimate Burger - Best Burger Recipe

Trust me on this one. Best burger ever. I like to put the burger on a toasted onion bun and melt some swiss on it. Mix all these ingredients together and grill it.

1. Mix 1.25 lbs. of lean ground beef
2. 1/2 cup of uncooked Quaker Quick Oats
3. 1/4 cup of A1 Steak Sauce
4. One egg
5. 1/2 of an onion of your choice. Chop it fine.
6. Chop a 1/2 cup of baby spinach.
