In reply to farmer:
Whatever you do with your beans don't forget to triple cheese and triple butter it. Cheese in the beans, on the top then under the grill to melt it then on the top again but not melted. Butter on the toast, in the beans and then a wee dab on top. If you're hardcore you can go quad core on the butter and butter your plate as well...but it's not for everyone.
The joy of beans is that almost any other ingredient will make them better, but don't forget to triple cheese it. Along with the usual paprika, cayenne, chilli poweder and garlic it's worth keeping onion salt, celery salt, garlic powder and oregano for that authentic packet food taste and if you can get hold of some msg all the better (usually sold as umami powder in asian food shops).
If you're looking for healthy then med veg (peppers, onion, courgette etc) fried up with garlic and perhaps some bacon or a sausage makes a tasty meal...but don't forget to triple cheese it and some extra butter to make up for the vegetables.
