In a very lightly oiled frying pan (or you can use a little water instead) fry 2 large mushrooms (sliced), and 2 cloves chopped garlic, about 1tb dried basil, a cube of frozen (defrosted) spinach (or about 1/2 cup fresh)… then add about 1/2c water to about 1b gravy powder add that into the pan. Stir until thick and serve.
If making gravy to go with steaks, try this…. Fry the steak in a tiny bit of oil in a frypan, then once each side is browned, remove the steaks and put them on a plate to “rest” and add about 1/4 cup water and the mushrooms etc. to the pan, stirring to allow the baked on meat juices to form a gravy. Once that water has almost gone, add the gravy powder mix, and when that has thickened add the steaks back in (with any juices), and let them simmer in there for a minute or so, stirring the gravy around so it doesn’t burn, then flip them over for another minute or so to finish cooking the other side. (I find simmering the steaks in the gravy makes a really nice moist steak with delicious gravy)
