Turn your oven to 425°F (220°C). Clean and pat dry your sweet potatoes. Strip off most skin but leave some patches for extra texture. Cut potatoes into thin rounds about 3mm (1/8 inch) thick.

Cover a baking tray with parchment paper. Spread out your sweet potato slices so they don't overlap. Pour oil over them and dust with garlic powder, salt, and chili powder. Mix everything so the slices get coated all over.
03 -
Stick the tray in the oven for about 20 minutes. Flip the slices once around the 10-minute mark. They're done when they feel soft when poked. For extra crunch, broil them for a minute or two at the end. Then take them out.

Scatter black beans over your hot sweet potatoes and cover with grated cheese. Put back in the oven just long enough for the cheese to melt completely.

Pull the tray out and drop spoonfuls of salsa, sour cream or yogurt on top. Scatter avocado chunks and any extras like jalapeños, green onions, cilantro, or corn if you want them. Eat right away while everything's still warm.
