This is what I did:
Soaked and boiled up about 250g (half a bag) of dried cannellini beans
Put them in the slow cooker and add a jar of good tomato pasta sauce, a tin of chopped tomatoes, and some nice sausages (I used toulouse sausages).
Cook on low for 10 hours or whatever.
When you get in from work, transfer the contents of the slow cooker into an ovenproof dish.
Lightly toast 2 thick slices of bread.
Whizz them up in a food processor with a couple of cloves of garlic. If you feel you would like to add say, some lemon zest or oregano, I say bloody go for it!
Melt a nob of butter with a splash of olive oil in a frying pan. Add the garlicky crumbs and fry them for about 5 mins. Keep moving them around. When they are toasty, tip them over the sausage and beans and spread them out gently. Don't press them down though.
Bake in a hot oven for 30 mins.
