Choose your grill and tools
You have several choices when it comes to indoor grills. You can choose an electric countertop grill, such as a George Foreman Grill (one to consider: the George Foreman Evolve), which have an electrically-powered heat source beneath metal plates. They come in two different styles: contact grills, which have a top and bottom grill plate and close over the food to cook both sides at once, or open grills, which are a single flat surface, similar to a griddle, and usually have more surface space, although you'll have to flip your food to cook the other side. Electric models typically have adjustable temperature control and some models also have an indicator light to tell you when the grill's hot. Also look for removable nonstick grill plates, which are easy to clean.
Another choice is a stovetop grill or grill pan. You'll find heavy cast iron models that are wide enough to fit over two burners, or square or round pans that have raised grill lines in the base of the pan. I find that the two-burner models heat unevenly, since there are gaps in the heat source, and can be heavy and unwieldy to use. My suggestion is a grill pan. Look for a grill pan in which you can see the indentations of the grill lines on the underside of the pan; the raised lines will get hotter in a pan like this, rather than one that has a smooth bottom. A square grill pan, around 11 inches, will provide enough surface space to make four burgers or chicken breasts at a time, or a couple of good-sized steaks. Again, a nonstick surface is a plus.
Also helpful to have for indoor grilling are some tongs that have a silicone or rubberized coating on the tips (so you won't scratch the nonstick surface), a grilling brush for basting on glazes and a silicone or plastic turner spatula.
