Add the pesto, olive oil, and lemon juice to a jar or bowl.
Stir or shake everything together until it’s fully combined. Taste and add salt and pepper as needed.
Store in the fridge for 5-7 days.
Notes
The oil and pesto can separate, so make sure to mix really well until it's smooth and pourable. A sealed jar is the easiest way.Taste before seasoning. Pesto can be salty.Serve at room temperature. Olive oil can firm up in the fridge. Let the dressing sit out for a few minutes and give it a good shake or stir before serving.Use it as more than a salad dressing. This works on cold pasta salads, roasted veggies, cooked grains, or even as a spread for sandwiches or wraps.
