In a skillet, melt 1 tablespoon butter over medium-high heat.
Dice ½ an onion and brown in the skillet.
Open the ham and dice the ham. Add to the onion mixture.
Add the minced garlic and cook until fragrant, 30-60 seconds.
In the skillet, add chicken broth and the tortellini. Cover and bring to a boil. Cook for 12 minutes.
Pour in ¼ cup heavy cream.
Add 1 ½ cups frozen peas (more or less depending on your preference) and stir into the tortellini mixture.
Stir in ½ cup of shredded Monterey Jack cheese and season with salt and pepper.
Transfer the tortellini mixture from the skillet to a baking dish.
Top with the remaining Monterey Jack cheese and broil for about 3 minutes or until the cheese is getting bubbly. Be sure to watch it to make sure it doesn’t burn.
Serve immediately.
