lots of easy recipes out there I agree with sassy any allegries. Also do you want to grill or use the oven or pots and pans. What do you feel most comfortable with.
I had a cook out for the staff and pulled it off great many second trips back to the food which surprised me a little b/c most nibble at work and don't a whole lot.
most of the food I cooked, baked, and grilled is super simple but tasty.
