In a large skillet, over medium-high heat, crumble and brown lean ground beef until cooked through, about 6-10 minutes. Drain if necessary on paper towels. If draining return to skillet.
Lower heat to medium-low. Add cubed Velveeta, Rotel, and cumin if using. Stir while the cheese is melting, about 3 to 4 minutes.
Once melted and warm, add in Mexican Blend cheese. Continue to stir while the cheese melts, about 3 to 4 minutes.
Garnish with shredded cheese, cilantro, sliced black olives, or your favorite toppings and serve while warm with tortilla chips, celery, pork rinds, or carrots.
Notes
Tips: If you prefer, you can use a 32-ounce Velveeta in place of the shredded cheese blend.
