Brown the beef: Heat a large skillet over medium-high. Add the ground beef and break it up with a spoon. Cook until browned and no longer pink, about 6–8 minutes.
Drain excess fat if needed.
Season simply: Taste the beef and add a pinch of salt and pepper if your salsa isn’t very salty. Keep it light—salsa will add more seasoning.
Add the salsa: Pour the entire jar over the beef. Stir to coat and bring to a gentle simmer.
Cook 3–5 minutes to let the flavors meld and slightly thicken.
Stir in the rice: Add the cooked rice and fold it in until evenly combined. If rice is cold, break up any clumps. Cook 2–3 minutes, just until everything is hot and steamy.
Adjust texture: If it seems dry, add a splash of water or broth.
If it’s too saucy, let it simmer uncovered for another minute.
Finish and serve: Turn off the heat. Squeeze a little lime over the top if you have it. Serve as is, or add shredded cheese, cilantro, or avocado.
