Preheat oven to 350 degrees.

Heat up a pan on medium heat. Add ground beef and cook, occasionally stirring until no longer pink. Drain out any liquid.

Add water and taco seasoning packet to ground beef and cook for 1-2 minutes until water evaporates.

Remove ground beef pan from stove.

Take out a 9x13 pan and spread a thin layer of salsa on bottom, then add 3 lasagna noodles covering it. Continue to layer the lasagna as follows: salsa, refried beans, ground beef, sour cream, Mexican cheese, and lasagna noodles. Repeat until all lasagna noodles are used up.

On the top layer, spread an even layer of salsa and Mexican cheese. Top with whites of green onions.

Cover the Taco Lasagna with foil and cook for 25-30 minutes until heated through.

Uncover and cook for another 5 minutes. This will melt the cheese on top.

Remove from oven and top with dollops of sour cream and spread remaining green onions on top.

Eat immediately or store in the refrigerator for up to 3 days, reheating prior to eating.
