Wash the pumpkin thoroughly with the skin on and cut it into bite-sized pieces.
Cut the chicken breast and tofu into bite-sized pieces.
Add olive oil to a pan and cook the chicken breast first.
Once the chicken is cooked, add the pumpkin and tofu and sauté lightly.
Season with salt and pepper.
Place the sautéed ingredients in an oven-safe dish and top with cheese.
Bake at 180°C for 10 minutes or until the cheese melts.
