Place all dressing ingredients except for pickle relish in a blender or food processer, blend to combine. Add relish, stir by hand to combine and set aside
Turn on the broiler in the oven, arrange french fries on a baking sheet, and sprinkle on ground beef and onions, and lay the slices of cheddar on top. Place in the oven and broil until the cheese melts, about 5 minutes.
Remove from the oven, and top with pickles and thousand island dressing, leaving some to dip in!
Notes
If you’re having trouble with the cheese melting you can try spraying with cooking spray before broiling, or you can melt the cheese in a small saucepan with a splash of vegan milk and pour it over the fries instead.
