So...keeping that in mind, if you look at the palm of your hand -- all of it, from where it meets your wrist, all the way around (except the fingers) that is about the same size as 3-4 ounces of steak. So, twice that much would be 6-8 ounces. Don't forget -- that's UNcooked. When steak cooks, it gets smaller.
A medium heat should be used when grilling chicken. Using too high of a heat will cause some parts to cook too quickly and dry out while other parts will not be done all the way through. To check the temperature of the grill, see Estimating Heat Level to see how to use the palm of your hand for testing.
