In a large skillet, brown the ground beef over medium heat until no longer pink. Drain excess liquid.
Add 1 cup of water, minced garlic, and taco seasoning. Cook for 1-2 minutes while stirring.
To a slow cooker, add the ground beef mixture, frozen potatoes, cheese soup, salsa, and ½ the shredded cheese. Stir to mix.
Cover and cook on low for 2-3 hours.
Before serving, add the remaining cheese and cover for 5 minutes to melt.
Serve with fresh chopped cilantro or sliced green onions.
