Preheat your oven to 375 degrees f. and line two large baking sheets with parchment paper.
Slice your sweet potatoes lengthwise into 1/2-inch-thick slices and sprinkle with sea salt, pepper, Italian seasoning, garlic powder, and a drizzle (or spritz) of oil.
Toss with your clean hands to evenly cover with oil and seasonings, then spread them evenly onto your prepared pans, allowing space between each.
Bake for 20 minutes, flipping halfway, until golden brown and crispy.
Top your potato crusts with pizza sauce, mozzarella, chicken, jalapeno, and olives as desired.
Turn your oven to BROIL and broil for 3-5 minutes, or just until the cheese is melted and golden on top.
Sprinkle with crushed red pepper flakes if desired.
Enjoy!
