Chipotle Burgers with Avocado Salsa

1 bunch fresh cilantro, chopped

1 pound ground beef

1 (7 ounce) can chipotle peppers in adobo sauce

1 cup chopped fresh mushrooms

1 tablespoon Worcestershire sauce

1 avocado - peeled, pitted, and diced

1 onion, diced

1 tomato, diced

2 jalapeno peppers, seeded and chopped

1 lime, juiced

salt and ground black pepper to taste

4 onion rolls, split

Preheat an outdoor grill for medium-high heat and lightly oil the grate.

Place half the chopped cilantro into a large bowl and mix with ground beef, chipotle peppers in adobo sauce, mushrooms, and Worcestershire sauce. Set remaining cilantro aside. Form the beef mixture into 4 patties.

Lightly toss remaining cilantro in a bowl with avocado, onion, tomato, jalapeno peppers, lime juice, salt, and black pepper.

Grill burgers on the preheated grill until browned and no longer pink inside, about 5 minutes per side. Serve the burgers on onion rolls topped with avocado salsa.
