Method
 

Preparation
  1. Gather all ingredients.
  2. Chop vegetables uniformly for even cooking.
  3. Rinse and drain canned beans to reduce salt.
Cooking
  1. Brown ground beef in a skillet with the chopped onion and minced garlic until no longer pink; drain excess fat.
  2. Layer in slow cooker: start with half the sliced potatoes, then half the beef mixture, half the beans, half the corn; repeat the layers.
  3. In a bowl, mix the condensed cream of mushroom soup with milk, diced tomatoes with green chilies, chili powder, salt, and black pepper; pour evenly over the layers in the slow cooker.
  4. Cook on low for 6-8 hours, until potatoes are tender and flavors are melded.
  5. Sprinkle shredded cheese over the top, cover, and let sit until the cheese melts (about 5–10 minutes).

Notes

Serve with fresh cilantro, sliced green onions, or sour cream for added brightness. Cool leftovers to room temperature and store in an airtight container in the fridge for 3-4 days or freeze for 2-3 months.
