Step-by-Step Instructions

In a large skillet, you’ll want to brown your hamburger onion. Be sure to drain any excess fat!

Next, stir in the taco seasoning, tomato sauce, RO-TEL (diced tomatoes and green chiles) and the water. Bring this mixture to a boil.

Then, break the spaghetti in half and add to the sauce and stir. Reduce the heat, cover and allow to simmer for 10 to 15 minutes, or to desired tenderness.

Sprinkle the cheese over the top. Cover until cheese is melted.

Garnish with plenty of fresh cilantro, if you like it!
