Warm the apricot (or strawberry) preserves in the microwave for about 15-20 seconds.
In a bowl, whisk together the warmed preserves, Dijon mustard, apple cider vinegar, and olive oil.
Season with salt and pepper to taste.
Add crushed red pepper flakes if desired for some heat.
Whisk or shake the dressing together, taste, and adjust anything as needed.
