Finely chop each herb, especially the rosemary. Then chop the onion and garlic.
Place the finely chops herbs, garlic, and onion into a small food processor, then add the freshly pressed lemon juice, salt, black pepper, and 1/4 cup avocado oil. Pulse it a few times until the mixture becomes finer.
Transfer the herb mixture into a small bowl and whisk in the remaining 1/2 cup avocado oil. Serve with warm bread. Store in an airtight container in the refrigerator.
