In a large ovenproof skillet, melt butter over medium heat. Add the onions and cook until soft and golden brown.

Add the ham and continue to cook until lightly browned.

Next, add in the chicken broth, tortellini, and salt and pepper to taste. Stir well to combine and bring to a boil.

Cover, reduce to a simmer for 12 minutes until the tortellini is tender.

Stir in the peas and cream. Remove from heat and stir in 1 cup cheese until well combined.

Top with remaining cheese, then place under the broiler in the oven until cheese is golden and bubbly, about 3 minutes. Serves 6.
