Cook peas in salted boiling water until tender, 1 minute. Transfer to an ice-water bath; drain.
Pulse peas in a food processor with mint, lemon zest and juice, garlic, 2 tablespoons olive oil, and tahini.
Season with salt and pepper; drizzle with oil.
This was good and made a ton. If you don't keep tahini around, you could add another clove of garlic and up the lemon juice for more flavor.
