Preheat the oven to 450 degrees F.
Slice off the 4 long sides of each of the sweet potatoes so the potatoes are squared off and sit flat on a cutting board. Slice the potatoes lengthwise into 1/2-inch-thick planks, about 5-inches-by-2-inches (you should get 3 planks per sweet potato). Combine the sweet potatoes, coconut oil and a pinch of salt in a medium bowl and toss gently to coat. Spread them out on a baking sheet and roast, flipping halfway through, until lightly browned and tender when pierced with a knife, about 15 minutes. Remove the sweet potato toasts to 2 plates.
Divide the almond butter among the toasts, then top each with sliced banana and sprinkle with toasted coconut. Serve immediately.
You can make the toasts in advance and refrigerate them in an airtight container up to 4 days. Reheat in a toaster until warmed through.
