This is quick and simple, especially if you have a toaster oven (no pre-heating).
Sweet potato oven fries:
-1 or more sweet potatoes, scrubbed but not peeled
-1 tbsp. olive oil (or more if needed)
-Salt and pepper, to taste
Cut the ends off the sweet potatoes, then slice it lengthwise into slabs about 1/4" thick. Cut each slab into thin strips, roughly the shape of fast-food french fries. Toss the fries with olive oil, salt, and pepper, then spread out on a single layer on a foil-lined baking sheet. Bake under a broiler for about 15 minutes or until the fries are browned and just a little bit crisp.
Spicy balsamic garlic sauce:
-1 tsp. your favorite hot sauce
-1 tbsp. balsamic vinegar
-1/2 tsp. soy sauce
-1 small clove garlic, minced
Mix ingredients until well combined and serve with sweet potato oven fries.
Sweet potato fries are also good with ketchup spiked with spicy paprika or cayenne. Mmm.
