Welcome to the forum, Tony, from NE Ohio!
For your first cook on your new Rec Tec mini? I think chicken is a great place to start. It'll let you get a feel for how the grill operates without having to wait for a weekend for something like a pork shoulder that takes hours to cook.
Spatchcock or split the chicken in half, season it up and cook it at 350° - 400° until done (Internal Temp of 165°).
