Step 1

Put the zucchini in a medium sauce pan. Add chillies (and tomatillo, if you using) and cover with water.

Step 2

Bring to a boil over medium heat and cook until zucchini are tender (about 5 minutes). Strain and let the ingredients reach room temperature.

Step 3

Place the zucchini and chillies (and tomatillo) into a blender. Add cilantro, garlic, onion and a teaspoon of salt. Pour in the oil.

Step 4

Pour 1/4 cup of water. If you use tomatillo, don’t need to add water. Then blend until you have a smooth sauce.

Step 5

Taste for salt and then transfer to a container. Enjoy!
