To make a barbecue spice blend, combine chili powder, coconut sugar, sea salt, garlic, paprika, cumin, mustard, black pepper, and cayenne in a small bowl.
Thinly slice the zucchinis into 1/8 inch slices.
Mist the olive oil over the zucchini slices, sprinkle the spice blend over the zucchini slices, and bake for 40 minutes.
Remove from the oven, flip the slices, mist a little olive oil on the other side, and sprinkle the splice blend over the other side too.
Bake for 20 minutes more, watching closely not to overbake.
