I read some of the comments before I made this to get an idea of what people did to make it their own. This is what I did.
*The spices I used were a little salt, fresh ground pepper, garlic powder.
*I included more cheese, and a variety when melting into the hot milk. I added 3 wedges of swiss laughing cow, 1/4 cup shredded parm. I used 2% sharp cheddar for the shredded. I also thought afterwards that I could have used light cream cheese and added a tad more shredded cheddar, to make a tad creamier.
*added a can of diced tomatoes (no added salt tomatoes) with the sauteed spinach as the layer between the mac.
*added 2 tsp of oil with the panko to make sure it would evenly brown, as well as mixed with another 1/4 cup of parm.
My mom who is a mac and cheese fiend, and also not a fan of whole wheat anything, absolutely loved this. She did say that she wished it was a little creamier, so will add more milk and more cheese next time. And also some sauteed onions with the spinach and tomatoes.
For those weight watcher people, this is only 5.5 points plus per cup!
