I cannot speak enough praises for this dish! If you have a picky eater who won’t come close to most greens, give this a try. It is warm and creamy and super cheesy. Every time I have served this, everyone has gone back for seconds. It’s that good, and it is super easy!

As always, I leave the decision as to what cheese to use up to you. Pictured is my batch using a colby jack and cheddar mix. I used zucchini and onion from my garden, so for me this was extra affordable. As promised, I will include fair market prices to give an accurate cost reflection for you, given that zucchini is my flavor of the week. You could easily make this a single dish meal as is, or add a protein in. This recipe is low carb and fits into a keto diet as well. Give it a try!
