Place the frozen peas in a large sieve and run under cold water for about 1 minute to thaw. Drain thoroughly and transfer them to the bowl of a food processor.
Add the remaining ingredients, except the garlic, and process until creamy, about 30 seconds. Scrape down the sides, add the grated garlic, and process again for a few seconds until fully incorporated. Taste and adjust seasoning.
Spread the hummus across a large plate or wide bowl. Drizzle with olive oil, sprinkle with the toppings of your choice and serve with crudité.
