If you're into meal prepping, then you'll want to incorporate this tactic into your practices as needed. This not only saves time when cooking, it will also help you stretch your herbs a little further and give you the perfect blend of oil and herbs each time.
All you need to do is grab an ice cube tray and mix together your oils of choice; mine happen to be organic avocado and coconut oil. Then, chop up your desired herbs (rosemary, thyme, parsley, basil, etc) and add to your oil mixture. Stir gently and pop them into the freezer overnight.
When you're ready, take them out, place in your pan, let melt and enjoy!
