You can substitute chicken tenderloins with bacon or other meats. Instead of tomato puree, you can use ketchup + Sriracha.
Cover frozen sweet pumpkin with plastic wrap, poke holes, and microwave for 4 minutes.
Heat oil in a pan, add chicken tenderloin and finely chopped onion, sauté, then cut the chicken tenderloin and season with pepper.
While doing step 2, transfer the microwaved sweet pumpkin to a gratin dish, mash it, add 3T allulose and 2T unsweetened almond milk, and mix.
In a pan, add tomato puree, 0.5T chicken stock, 0.5T minced garlic, 1T allulose, pepper, and chopped mushrooms, stir-fry.
Spread everything sautéed in the pan over the gratin dish, sprinkle cheese on top, and cook in an air fryer at 180°C for 10 minutes.
