Cook the tortellini in a pot of boiling water, according to package instructions.
Meanwhile, heat a large skillet over medium-high heat and cook the ground beef with the diced onion, breaking up until crumbled and no longer pink. Drain any excess fat from the pan and return to skillet to stove top.
Add in the chili powder, garlic salt, cumin, oregano, enchilada sauce, salsa and corn to the ground beef mixture. Bring mixture to a simmer, then stir in the shredded cheese and sour cream until sauce is creamy.
Drain the tortellini and add it to the cheesy, beef mixture. Stir to coat. Garnish with freshly chopped cilantro if desired. Enjoy!
Notes
*If using dried tortellini, you'll want to use about 1 1/2 cups of dried tortellini so when it's reconstituted it'll be about 12 oz.
