Garlic and Walnut Sauce for Pasta

2 slices stale bread, crusts removed
2 tbsp stock, warmed
1 cup walnuts, toasted
1/2 cup parsley, stems trimmed
3 medium garlic cloves, chopped
1/2 tsp Salt
1/8 tsp black pepper
6 tbsp olive oil

Soak the bread in the stock & then squeeze out any excess moisture. Combine the bread with the walnuts, parsley, garlic, salt & pepper in a food processor. Process, adding the olive oil in a very slow stream until you have a thick paste. Toss with your favourite pasta & serve hot.
