    I cut recipe in half, using two 7-oz. cans of Rotel which gives me 14 oz. of tomatoes. Very good recipe.

    Yummy and super fast. I modified a bit as we are moving and a lot of my stuff is already packed. So I subbed ground breakfast sausage, taco seasoning, chili powder and a little leftover spaghetti meat sauce for the ground beef, tomato sauce and other seasonings.

    This is a wonderful way to use boxed mac & cheese to create a very budget friendly dinner the kids just love! My kids gobbled this up, and didn't complain about having left overs the next day. So it reheats pretty well. This is tasty, kid friendly, and cheap. I give it 4 out of 5 stars only because it's not the most nutritious meal. Tons of calories and fat, not to mention high in sodium. But for a once in awhile "I'm in a pinch" kind of dinner, it's perfect!

    Excellent meal! I halved the recipe for just the two of us, and have plenty for another meal. My husband is thrilled. I added some fresh diced jalapeno because we love spicy, and a few crushed chips on the top, but other than that I made as the recipe stated. Quick to put together and so delicious!
