Lupin Free Apple-Sage Sweet Potato Crostini
These little bites are the kind of appetizer that disappears from the platter before you've even finished arranging them. Roasted sweet potato rounds stand in for bread, getting beautifully caramelized in a hot oven with coconut oil and a whisper of turmeric, then topped with a warm skillet mixture of diced apple, fresh sage, shallot, and warm spices. A splash of apple cider vinegar and a drizzle of honey pull the whole topping together into something that's sweet, savory, and just a little tangy all at once. Every single ingredient here is straightforward and naturally free from lupin — no flour blends, no legume-based fillers, nothing that tends to sneak into store-bought appetizers and crackers. Ceylon cinnamon and ground ginger give the apple topping a gentle warmth without overwhelming the fresh sage, which is genuinely the aromatic star of the show. A pinch of flaky sea salt at the end ties everything together and makes each bite feel a little fancy. Whether you're serving these at a dinner party or just treating yourself on a weeknight, they're an impressive, fuss-free option that happens to work beautifully for anyone navigating lupin sensitivities.
