After reading all reviews, here's what I did to make this taste awesome. Dice an onion (can add garlic too if desired) and brown meat w/ a little salt/pepper. Cook 2 boxes of mac and cheese separate (yes, two boxes will be better than one if you have two). Add 1 tblsp sour cream to mac and cheese when finished and mix it in. Add 1/2 taco mix to ground beef (don't add more or overdo it, will be too strong) add a bit of water (1/2 cup to a cup) to mix it, add 1 to 2 tblspn Heinz ketchup (it will taste good, don't worry), and three tablespoons salsa to ground beef and mix altogether. Finally, add mac and cheese to ground beef (or ground beef mix to mac and cheese pan). Viola, you're done! It tastes amazing - husband and I both loved it!
