Fry some sliced onions until golden-brown. Make up some beef stock, a cube will do, and add a splash of red wine, and lots of black pepper. Mix all together and reduce by half.
Grill or fry the steaks to your liking, (I usually rub them with a little crushed garlic.) Pour the sauce over the steaks. I personally like English mustard with this, the combination is good. This is great with French Fries, and a green salad, I like Little Gem Lettuce, with a vinaigrette. As a change from chips, you could try a couple of Aunt Bessie's frozen Yorkshire puddings, they soak up the sauce, and it is heaven!
