This looks gross, but it's absolutely flavorful and yummy--and satisfies your umami quotient. I made the spinach pesto the other night. Here's my typical haphazard (but easy) recipe:
1/2 cup spinach
1/3 cup sliced almonds
2 cloves garlic1/3 cup sundried tomatoes packed in oil
1 cup oil
1/2 cup grated parmesan
1/2 tsp lemon zest
2 tbsp lemon juice
salt and pepper to your fabulous taste
Combine all the ingredients (except the parmesan and oil) in blender. Gradually add the oil, maybe a tablespoon at a time. Blend/puree until the consistency of chunky paste (yum). Add salt and pepper. Put in bowl, then pour in the grated parmesan and blend with a fork--the consistency is chunkier and the flavor more nutty this way. Top your toasted pita with it.
That's it! Don't choke on it (as you gobble it down).
