Whisk all the ingredients together in a small food processor, or use a clean jar and lid and shake it (you can also just whisk together in a bowl or jug with a small whisk or fork).
½ cup olive oil, 1 tablespoon vinegar, 2 tablespoons honey, 2 limes, 1 teaspoon mustard, 1 tablespoon onion, salt and pepper
Toss through a salad, drizzle over vegetables, or use as a marinade. Store any leftovers in the fridge in a sealed jar or container for up to about a week.
Notes
Limes: Add juice/zest of 1 lime to start with, then taste and add more if you like. I find 1 lime is about right for a dressing/vinaigrette for a salad, but I prefer more lime for a drizzle e.g. for halloumi kebabs or a lunch bowl, or a marinade.Storage: Use a clean jar with a lid to shake up all the ingredients together. You can store any leftover dressing like this in the fridge for up to a week.If the olive oil solidifies in the fridge, simply take it out of the fridge for a while before using.Variations: Add a spoonful or two of Greek yogurt for a creamier dressing, or a version that works particularly well as a marinade. Feel free to skip the mustard and/or the onions if you'd like to make an even simpler version.Making a marinade: To use this lime honey dressing recipe as a marinade, I'd suggest doubling all the ingredients (you can still stick with just 2 limes). Use to marinate your meat in the fridge for at least an hour, and up to overnight.
