Using a mandolin slicer on the thinnest setting, slice all the zucchini and squash into rounds.
Place into large ziplock bag or bowl and add olive oil, salt and pepper. Shake to coat well.
Preheat the oven to 325F.
Line a large baking pan with parchment paper or a Silpat mat.
Place zucchini and squash rounds onto baking pan and bake for about 25 minutes or until they start to get golden brown.
While the chips are cooking, mix together all the ingredients for the honey mustard in a small bowl and whisk together.
Top chips with chopped parsley and serve with honey mustard dipping sauce.
