Grilled onion salad with rosemary FAQ:

What type of onion is best for grilling?

While you can use any onion, yellow onions are ideal for grilling due to their sweetness and flavor. Red onions also work well if you prefer a milder taste.

How can I tell when the grilled onions are done?

Grilled onions are done when they are tender and have grill marks on both sides, typically after 4-6 minutes of grilling per side. They should be soft but not burnt.

What can I substitute for olive oil in the dressing?

If you need a substitute for olive oil, you can use avocado oil or canola oil in a 1:1 ratio. However, the flavor may differ slightly from traditional olive oil.

How should I store leftover grilled onion salad?

Store leftover salad in an airtight container in the refrigerator for up to 3 days. Reheat gently in the microwave or serve cold, as the flavors will continue to develop.

Can I make the dressing ahead of time?

Yes, you can prepare the dressing up to 3 days in advance. Keep it in a sealed container in the refrigerator. Whisk it again before using, as it may separate.

Tips:

- When grilling the onions, make sure to slice them uniformly to ensure even cooking.

- If you don't have a grill, you can also roast the onions in the oven at 400°F (200°C) until they are caramelized and tender.

- For a stronger rosemary flavor, let the dressing sit for at least 30 minutes before using, allowing the herbs to infuse the oil.

- Adjust the amount of mustard to your taste if you prefer a milder or stronger mustard flavor.

- Add a sprinkle of fresh herbs, such as parsley or chives, for an extra burst of freshness.
