Okay, so I received my grill pan and press and am so excited to use it and make some Paninis and I just look at it and have no idea what to do! My husband keeps asking me all these questions and I don't know. Now, granted I haven't completely went through the website or the card that came with it (have been sick and didn't feel like reading) but I thought I'd come straight to the experts... Please tell me exactly how to do this... remember I need details! Do you have to heat the press up and if so how? That's the main question I guess, but I just need details.. TIA!!
