Have you tried bouillon - I sprinkle it over the veggies and chicken or quorn and bake - or kind of stew it in a liquid version
Also try the soups made up as a sauce - the chick/mush, mush and cheese and broc work well - make to custard consistency and nuke in microwave for 1 min and pour over meat, mmm
Also cajun spices, and various other spices are often mentioned on here - I don't use them but I am sure they are nice
good luck xx
