Everything is of course flavour preference but I found that liquid smoke is a great add-on that makes much veggie food taste good to meat eaters; it takes care of the smokey/charred flavour that you get using ham or frying your meat before you add other things. And for umami tomato (fresh/canned & condensed) works wonders.
