Cut an onion in half and pull off 2 garlic cloves.
Peel back the flaky onion layer. I like to use the "root" end to hold onto while grating the onion. Chop the garlic clovers.
In a mixing bowl, combine the ground beef, grated onion, minced garlic, mashed pinto beans and taco seasoning. Combine and form into 6 patties.
Grill the patties, until cooked through. Serve on buns with a spoonful or two of salsa on top.
Prepare dressing and salad.
Serve Beef & Bean Burgers with side salad.
