Preheat oven to 400 degrees and line a baking sheet with parchment paper.

In a large bowl toss the spiralized sweet potatoes with the olive oil, chili powder, salt and pepper until completely coated.

Pour the sweet potatoes out onto the prepared baking sheet and spread out into a single layer.

Bake for 20 minutes gently tossing halfway through to ensure even cooking.

Check the sweet potatoes after 15 minutes as they may brown faster depending on the their size and your oven.

While the sweet potato fries are baking heat a large skillet over medium heat.

Add in the tablespoon of olive oil and swirl it around the bottom of the skillet.

Add in the onion, sugar, salt and pepper tossing together to coat everything.

Let the onions sauté over medium heat for about 7-8 minutes then reduce the heat to medium low.

Let the onions cook for another 10 minutes or until they are brown and caramelized, stir occasionally.

In a small bowl whisk together the ketchup and chipotle pepper in adobo sauce until combined.

Heat the Sweet Earth Santa Fe Veggie Burgers according to box instructions.

Toast the buns if desired and lay a piece of lettuce on the bottom of the bun.

Place the burgers onto the lettuce and top with a slice of pepper jack cheese and equal amounts of the caramelized onions and sweet potato fries.

Spread some of the chipotle ketchup on the top half of the bun.

Serve immediately.
