This many people have eaten here:
Spinach-Walnut Pesto
1-1/4c. packed, stemmed & ribbed spinach leaves,
thoroughly washed
1c. olive oil
1c. grated Romano cheese
1c. shelled walnut pieces
2 med. garlic cloves (for garlic lovers like me & Ed, use 5)
2 tbsp. lemon juice
3/4tsp. salt
Put all into a food processor or blender with metal blade.
Pulse several times until coarsely chopped.
Then process until sauce is as smooth/coarse as you want.
If it seems too thick, add a little hot water.
