Canned chopped tomatoes will stretch any soup or casserole that bit further which is great if an unexpected guest stays for dinner.

To pep up a normal Shepherd or Cottage pie I add a can of toms to the cooked seasoned mince with two teaspoonfuls of curry powder so that there is a little heat but not too much. Top with either mash potato or parboiled potato slices, smear the top with butter (not healthy I know, optional) to brown it off.
