Wash and dry the chosen herbs or spinach.

Chop the leaves into small pieces and add them to an empty ice cube tray or 2 tablespoon Souper Cubes Tray. Pack each cube with individual herbs.

Cover each cube in your oil of choice; avocado or olive oil work best.

Place the tray in the freezer for 6 to 12 hours.

Pop out the cubes and store in a freezer-safe bag.

To use, add oil cubes to the hot pan. If using cubes in a cold dish like tzatziki, remove the cube from the freezer and let it come up to room temperature before stirring into mixture.
