What is Jim doing? Grilling beef

Question 21 - 23 refer to following paragraph:W: Hello, Jim. I just finished preparing these sandwiches
M: Thanks, Allie. That’s so nice of you.
W: it was quite a simple recipe. I roasted some vegetables and added them to a couple of slices of baguette
M: That will be a great appetizer as the guests are arriving, and I will go nicely with the beef kebabs I’m grilling. Why don’t you set them on the coffee table in the living room next to the fruit?
