In a food processor, combine the defrosted frozen peas, optional pea shoots, grated parmesan, olive oil, fresh lemon juice, minced garlic, salt, and pepper. Pulse until you achieve a coarse pesto texture, about 15-20 seconds.

Preheat your oven's broiler. Slice the ciabatta bread into thick pieces and place them on a baking sheet. Drizzle each slice with olive oil, then toast under the broiler for 2-3 minutes on each side until golden brown.

Rub each slice of toasted bread with a peeled garlic clove to infuse aromatic garlic flavor.

Spread the prepared pea topping evenly over each slice of toasted ciabatta. Garnish with extra grated parmesan, lemon zest, and pea shoots.
