Chop the onion and add to the mince. Pour in the baked beans with tomato sauce.
Add some cream (I never measure, just add until it looks tasty).
Add some pepper and salt to taste.
Add tobasco and chives (optional)
Heat well and pour in an oven dish. Sprinkle grated cheese and breadcrumbs over the dish. Drop a few small lumps of butter on the top. Put the dish under the grill until the cheese and breadcrumbs look nicely browned. Lovely with a fresh letuce salad.
