In a medium skillet over medium-high heat, add 1 tablespoon of extra virgin olive oil. Once the skillet is hot, add ground beef, garlic powder and 3 tablespoons of salsa. Cook until the meat is browned (about 8 to 10 minutes). Drain the excess grease. Set aside.
Add the cooked pasta to a large salad bowl. Add the beef mixture, tomatoes, red pepper, green onion, cilantro and cheddar cheese. Mix to combine.
Add ¼ cup olive oil, 1 cup salsa, cumin, chili powder, oregano, salt and pepper. Stir until everything is combined. Chill in the fridge until ready to serve. Serve cold.
