Makes about 6 servings (1 serving is about 2 heaping tablespoons)
(ever so slightly modified from Cooking with Amy‘s version).

Ingredients
1 cup frozen peas
2 cloves garlic, chopped fine
2 Tablespoons olive oil
2 Tablespoons parmesan cheese
1 Tablespoon minced walnuts (optional)

Directions
In small saucepan combine garlic and green peas, with just enough water to cover. Bring to boil over medium heat, then lower heat to simmer and cover the pan. Cook for 3 minutes or until peas are cooked through and garlic is no longer raw.

Drain the peas, reserving the water. Place peas, nuts, and olive oil in blender and blend, adding just enough water to make a smooth paste (about 1 tablespoon).

Combine mixture with parmesan cheese. Serve over cooked pasta.
