Mini Farfalle with Garlic and Onions

Here's a twist on a side dish I usually make with orzo. I was all set to make it tonight, and had already defrosted the chicken broth, when I discovered that I didn't have any orzo. So I improvised--and it was good!

1 small onion, chopped fine
2 tsp minced garlic
2 tbl olive oil
2 cups chicken broth
1/2 tsp dried thyme
2 cups mini bow-tie pasta
1 cup frozen peas
1/2 cup Parmesan cheese

Saute the onion and garlic in the olive oil. When everything is soft, add the broth and thyme. Bring to a boil. Add pasta and peas, bring to a boil, then turn down to simmer and cover. Simmer 20 minutes. Stir in cheese and serve immediately.
