How to Make Boxed Mac & Cheese a Little Better

I know it is not healthy. I know there are chemicals in that "cheese". But sometimes you gotta do what you gotta do. So, I sort of make it according to the directions on the box.  BUT to help with the protein, I add a 1/4 cup dried red lentils along with the noodles during the boiling process. Both the noodles and lentils are done within 7 minutes. Meanwhile, either drain a can of diced tomatoes or chop up about 4 plum tomatoes. Five minutes into the boiling process, add a couple of handfuls of chopped kale. Feel free to use spinach too.  At 7 minutes, drain in all saving about 1/4 cup of the cooking water.  Returning the noodles to the pot, add the "cheese" to the noodles/kale/lentil mixture, a tsp of butter and the 2Tbsp milk and 2Tbsp reserved liquid (or all milk or all liquid) and stir. Once it's as well blended as it'll get, add the tomatoes. Put on low heat and cook through until the tomatoes are warm. Top with some fresh cheese. You've added protein and vitamins to an otherwise not very nutritious meal. Bon appetite!
