In a medium bowl, mix all the ingredients together. Taste, then adjust the amount of lemon juice, garlic and/or salt to suit your preference.
Cover and chill in the refrigerator for at least 30 minutes to allow the flavours to blend. Store leftovers in a sealed container in the refrigerator and eat within 4 days.
Notes
How to adjust the flavours: if you need more overall flavour, add salt. If you want a stronger lemon flavour, add more lemon juice. And if you want more bite, add a bit more garlic.
