In a food processor, blend the white beans, lemon juice, garlic, lemon zest and salt, scraping down the sides as needed. With the food processor still on, slowly stream in the sage infused oil. Taste to see if you need more sage flavor. If so, add a few sage leaves at a time. I added 3 large leaves to mine, but there's a wide range in sage leaf sizes. You may even prefer the dip with no leaves, only the infused oil. Sage has a very strong flavor, so add it gradually, tasting after each addition.
