In a 12-inch skillet over medium-high heat, brown the ground beef and onion until meat is fully cooked. Drain excess fat.
Add minced garlic, chili powder, cumin, and salt to the skillet and cook for 60 seconds until fragrant.
Pour in the red enchilada sauce and beef broth, stirring to deglaze the bottom of the pan.
Add the refrigerated tortellini and stir to submerge in the liquid.
Reduce heat to medium-low, cover the skillet, and simmer for 7 minutes or until the tortellini is tender.
Distribute the shredded cheese evenly over the surface. Cover for 2 minutes until the cheese is melted and bubbly.
Garnish with chopped cilantro and serve immediately.
