Hamburguesa mexicana

Today was an easy lunch. We had Mexican Hamburgers and oh boy, they were so good I can't wait to make them again. Here's the recipe for 2 servings, but From 1/2 lb. ground beef you can easily make 4 patties for four people, just add one more avocado, tomato and a little bit more lettuce.

1/2 lb. ground beef
3 tb bread crumbs
1 egg
1 onion, minced, divided
1/2 cup mozzarella cheese
1 jalapeño pepper
2 tomatoes, chopped and juices strained
1/3 cup cilantro, chopped
1/3 cup red & green bell pepper, chopped
1 lime
1 avocado
1 1/2 cup iceberg lettuce or Romaine, cored and shredded
2 hamburger buns
Salt and ground pepper to taste

Directions
Mix ground beef, half the onions, bread crumbs, mozzarella cheese, jalapeño pepper, and eggs in a bowl; form into patties.
Combine tomatoes, half the remaining onion, cilantro, a quarter of each, red and green pepper, and half the lime juice; mix well to make pico de gallo. Cover and chill in refrigerator.
Mash avocado, remaining onions, and remaining lime juice together in a bowl to make guacamole. Season with salt and pepper.
Heat a skillet over medium-high heat; pan-fry burger patties to desired doneness, 3 to 5 minutes per side. An instant-read thermometer inserted into the center should read 160 degrees F (70 degrees C).
Assemble each sandwich by placing a burger in each bun; top burger with guacamole, shredded lettuce, and pico de gallo. Enjoy!
