Microwave the chicken according to package directions (there are also skillet directions if you choose that instead).
Slice the ham into smaller pieces. (about 1" pcs).
Stir the jar of sauce into the pasta. I usually turn the stove on low and add about 1/2 cup of water with the sauce (I actually fill the jar up with 1/4 cup of water, shake it hard to get ALL the sauce and then pour it all right into the pot).
Add the chicken and ham and stir to coat with sauce.
Add the wedges of creamy swiss and stir until melted.
Notes
In this healthier version, I was able to cut the calories almost in half, and the FAT by nearly 2/3! I cringe at the fact that we have eaten it the old way too many times. I prefer the flavor this skinny version has... it's FAR better.
