Pesto Tomato Sauce

V & I invented this one summer evening while making grilled pizzas. They were delicious, and so is this sauce. Variations: Regular & Roasted Pepper Pesto.
Ingredients

• 1 C fresh basil leaves
• 1/4 C walnuts
• 2 cloves garlic, or 2 tsp minced
• 2 Tbsp olive oil
• salt & pepper to taste
• 1/2 C prepared tomato pizza or pasta sauce (we used Pizza Quick b/c that's what we had on hand)

Instructions
Place all ingredients in a mini-food processor or blender, and puree into a smooth and creamy sauce. The color will be a kind of gross greenish brown, but it will taste outstanding! Use as you would any pizza or pasta sauce.
