You can use fresh or frozen peas instead of snap peas.
All the prep work can be done ahead of time and the ingredients wrapped in plastic and refrigerated. Cut carrots and wrap separately. Cut and wrap beef and onion together.
Add slices of provolone cheese over the top of the skillet after the pea pods are done. Remove skillet from the heat, and cover and let stand 1 to 2 minutes or until the cheese is melted.
