Easy Ham Roll-ups

I am going to try these in my son's lunchbox. Don't they sound yummy?

Ingredients
1 can refrigerated crescent roll dough
prepared honey mustard
4 to 8 thin slices ham, depending on size
4 rectangular Mozzarella cheese slices, or use shredded Mozzarella cheese
sesame seeds

Directions
Divide crescent rolls into 4 rectangles and press perforated seams together. Spread with the honey mustard. Top each rectangle with 1 slice of ham and 1 slice of cheese, or sprinkle with shredded cheese. Roll lengthwise, then roll in sesame seeds. Cut each roll into 6 slices and bake at 350° following crescent roll directions, or until browned.
