You can substitute chicken breast with bacon or other meats. If you don't have tomato puree, use ketchup mixed with Sriracha instead.
Wrap the frozen sweet pumpkin with plastic wrap, poke a few holes, and microwave for 4 minutes.
Heat oil in a pan, add chicken tenderloin and finely chopped onion. Stir-fry, then cut the chicken into pieces and season with pepper.
While doing step 2, transfer the microwaved sweet pumpkin into the gratin dish, mash it, and mix in 3T allulose and 2T almond breeze milk.
In the pan, cook tomato puree, 0.5T chicken stock, 0.5T minced garlic, 1T allulose, pepper, and chopped king oyster mushroom.
Pour all the stir-fried ingredients over the mashed pumpkin in the gratin dish, sprinkle cheese on top, and air-fry at 180°C for 10 minutes.
