As to the grill, yes you can use that as a grill for the steak but you would be better using a frypan on the top of the stove. The poster was referring to a grill where the flames/heat comes from below like a bbq grill. You won't get the same results from using the oven grill with a steak and you do risk stewing it if you don't know what you are doing.
Learn how to make savoury mince (beef mince, some water, seasonings like garlic, S&P, Worcestershire sauce and any vegetables that you do like all cooked together in a pot, mixing regularly until mince is cooked) cos then you can make tacos, spaghetti, mince on toast, put it in some puff pastry for a pie, top with mashed potato and bake for a Cottage Pie, top a jacket potato (prick washed potato all over, put in microwave for a couple of mins, then turn over and cook for a similar time until soft) with the mince, and top with some tomato sauce and cheese.
Get a fish fillet and put it in a freezer bag that you have put some flour, salt, pepper, garlic powder and dried tarragon. Shake the bag until the fillet is coated. Put a fry pan on low heat and put a good dob of butter in. When the butter has melted, put the fish fillet in. When the fish colour on its side has started to change to opaque, turn it over and continue to cook for a minute or so, depending on the thickness of the fillet. Remove from pan, remembering that the fish will continue cooking. If you want a sauce for the fish, deglaze the pan by pouring a splash of wine, sherry, verjuice or apple cider vinegar into the pan, turn up to high and mix the liquid with the pan juices and and crispy bits in the pan. Remove from heat and pour in a splash of cream, mixing well and pour over your fish. You can then serve the fish with chips/potato or anything else you desire.
