If using canned chickpeas, dump them into a pyrex measuring cup or other microwave safe container, add a bit of water, and cook in a microwave for 10 or more minutes at reduced power. The goal is to simmer them without boiling them over.
Combine Chickpeas, tehina sause, salt, and cumin in a food processor or blender. puree the hummus for several minutes until smooth and creamy.
Add additional lemon juice and salt to taste.
To serve, spread in a shallow bowl. Optionally top with Paprika, more tahina sauce, chopped parsley, whatever. Optionally add a drizzle of olive oil.
