This is one of my favourite meals, mostly eaten with jacket potatoes.
(in our house we never measure anything out, just work out how many people will be home for dinner and guess from there)
Chop and fry some onion with black pepper and mixed herbs until the onion is soft, add tinned baked beans and tinned tomatoes (two tins of beans for every tin of tomatoes) mix together and add soy sauce to taste.
Cook the sausages first and them either add them to the casserole and let them stand for a while to mix the flavours (it tastes best like this) or serve the casserole as it is with the sausages (useful if like in our house there are veggies and meat eaters.)
It’s also really nice reheated on toast for breakfast.
