Easy Spinach Sauce

1 package frozen spinach, cooked and drained of all water
1/2 cup vegetable broth
3 cloves garlic, more or less to taste
1 tsp onion powder
salt & pepper to taste

Put spinach, garlic and spices in blender and add 1/2 of the vegetable
broth. Blend until smooth, adding more vegetable broth if necessary (more
broth = thinner sauce). After blending, return to saucepan and heat until
hot. Serve over rice or pasta.
