Wash the zucchini and cilantro, then roughly chop the zucchini, onion, garlic, and cilantro.

Heat 1 tbsp cooking oil in a frying pan over medium heat, then add the chopped zucchini, onion, and garlic.

Sauté the vegetables for 10 minutes, stirring occasionally, until softened and lightly browned.

Transfer the softened vegetable mixture to a mixing jug and let it cool for about 5 minutes.

Squeeze the juice from half a lime into the mixing jug, then add the cilantro, salt, and black pepper.

Blend the mixture until completely smooth, then taste and adjust the salt, pepper, or lime juice if needed.

Serve immediately as a dip or spread, or refrigerate it in a sealed container before serving.
