Brown the ground beef. Add the ground beef and onion to a large pan over medium heat and cook until just browned and the onion is softened. Drain the fat is desired. Add the minced garlic and sauté for 1-2 minutes, stirring occasionally until the garlic begins to brown.
1 pound ground beef, 1 small onion, 3 cloves garlic
Add the spices. Add the cumin, smoked paprika, chili powder, ancho or chipotle if using, onion powder, black pepper, salt, and chopped jalapeno. Stir to combine and cook for 1-2 minutes.
1 tablespoon cumin, 1 tablespoon smoked paprika, 1 tablespoon chili powder, ½ teaspoon ancho chili or chipotle powder, ½ teaspoon onion powder, 1 teaspoon black pepper, 1 teaspoon salt, 1 large jalapeno
Simmer with tomatoes until tender. Add the diced tomatoes (Rotel), vinegar, water, and Worcestershire to the pan and stir to combine. Bring to a gentle simmer and cook for 10-15 minutes, stirring occasionally until the tomatoes are tender and the sauce has thickened. Season to taste with salt and pepper.
10 oz diced tomatoes, 2 tablespoons red wine vinegar, ⅓ cup water, 1 tablespoon Worcestershire sauce
Prepare the avocados. Cut each of the avocado in half lengthwise and remove the pit. Use a spoon to gently scoop a 1-2 tablespoons of avocado out of each half to make a sizeable well you can stuff the chili into. Make sure you leave as much meat on the avocado as possible while making room for the chili. The removed avocado can be used as a topping or made into fresh guacamole. Lightly rub each avocado with lime juice and sprinkle with salt. You can also fluff the avocado by dragging a fork across it to make room for the chili.
6-8 large avocados, ¼ cup lime juice, salt
Stuff avocados and serve. Fill each of the halved avocados generously with the chili and top with grated cheddar cheese, sliced green onion, fresh cilantro, guacamole, or sour cream. Serve and enjoy!
1 cup cheddar cheese, green onion, cilantro, ½ cup sour cream, guacamole
