Or you can add it to a buddha bowl or chickpea bowl. I've even been known to enjoy the leftovers as a snack.
Leftover roasted vegetables can be covered and refrigerated for 3-4 days.
Reheat them in a microwave-safe bowl or enjoy them cold straight from the refrigerator. This Dijon cauliflower is a wonderful addition to salads topped with Mediterranean Green Olive Salad Dressing.
Make sure to spread the florets out evenly on your baking sheet and avoid overcrowding to ensure even roasting.
More nutrients are retained with dry cooking methods such as roasting, grilling, and stir-frying.
This recipe can be prepared in your air fryer by cooking at 375 degrees for 20 minutes, tossing halfway through. Be sure not to overcrowd the basket. You may need to cook the florets in two batches.
