cheesy broccoli orzo

1 cup orzo
1-1/2 cups chopped broccoli florets
1/4 cup shredded cheddar cheese
2 Tablespoons grated parmesan cheese
1 Tablespoon butter
1/4-1/2 cup 2% milk
salt
Directions:
Add orzo to a large pot of salted boiling water. Cook for 3 minutes then add chopped broccoli and cook for 2 more minutes, or until orzo is tender. Drain well (broccoli florets are notorious for holding onto water) then return to the pot. Add cheeses, butter, and 1/4 cup milk then stir well and add more milk if needed. Season with salt to taste.
