1 lb. tortellini (any kind, I used whole wheat with cheese filling)
6 slices bacon, diced
6 tsp. unsalted butter
2 C. arugula (I substituted baby spinach)
kosher salt
black pepper

Cook the tortellini according to the package instructions. Meanwhile, cook the bacon in a large skillet, over medium heat until crisp. Reserve the bacon and discard the drippings. Wipe out the skillet and return to medium heat. Add the butter and brown (see how to brown butter below). Remove from heat and add the bacon, arugula (or spinach), salt, pepper and cooked tortellini. Toss well and serve.

How to brown butter: Melt the butter in a skillet or small saucepan over medium heat (preferably a light colored one, this helps to see the color develop). Stir the butter as it starts to foam. Remove from heat as soon as it starts to turn golden brown and smells nutty (about 1 minute).
