The problem with pizza and a being healthy is they don't exactly go hand in hand. It's usually pretty fatty and pretty carb heavy which is a bad combo if your goal is stay or get trim. This "version" of pizza was a random throw together that I did the other night and it turned out pretty good. I will say with the protein and fiber from the lentils this dish fares on the healthier side too.
In the dish I used a homemade pizza sauce. I have to apologize in that I have no idea what I added to it. I think I just googled "homemade pizza sauce" and semi followed a recipe. It's super simple especially if you start with a tomato sauce and not whole tomatoes. If you want to get really ambitious go for the whole tomatoes it will be worth it. Also the longer you can let it simmer the better but in a pinch 10 minutes will do. Just try to avoid adding sugar, there's no need!
I should also mention that I did this in our new Fagor pressure cooker. We love this addition to our kitchen and use it all the time for all sorts of dishes and foods. This could easily be done in a saucepan or deep skillet. I was able to saute in this then just add the lid and set the timer and walk away. Pretty slick!
*A variation if you aren't looking for a GF dish would be to transfer to a baking dish after lentils are cooked, top with cheese and then top with some Italian bread crumbs.
