Steps
- Peel, seed, and dice 4 green papayas. Boil in a saucepan of water until tender. Drain and mash; season with salt and pepper.
- Preheat the oven to 350°F / 175°C. Grease a 9 × 13in / 23 × 33cm baking dish.
- Brown 450g of ground top round beef in a skillet over medium heat. Remove, then fry 1 large sliced Bermuda onion in a little oil until softened.
- Layer the mashed papaya, 4 sliced ripe tomatoes, ¾ cup of tomato sauce, beef, onion, and 1 cup of grated cheddar in the dish. Reserve some papaya and cheese for the top.
- Finish with the reserved papaya and cheese. Cover with ½ cup of breadcrumbs. Bake for 40 minutes, until browned and bubbling.
