Legume Free Apple-Sage Sweet Potato Crostini
These little bites are the kind of appetizer that disappears from the platter before you even get a chance to announce what they are. Roasted sweet potato rounds stand in for traditional bread crostini, getting brushed with coconut oil and a whisper of turmeric before hitting a hot oven until their edges caramelize into something genuinely irresistible. The topping is where things get really special — diced apple sautéed with shallot, fresh sage, warm Ceylon cinnamon, and a splash of apple cider vinegar, finished with honey for a sweet-savory balance that feels both rustic and refined. Because the whole recipe leans on vegetables, fruit, and pantry spices, there's nothing here that sneaks in a legume under a different name — no hidden lentil flours, no chickpea-based binders, no soy lurking in a sauce. Every ingredient earns its place and does exactly what it promises. A pinch of flaky sea salt over the top right before serving pulls the whole thing together and makes each bite feel a little fancy without any extra effort. Whether you're building a grazing board or just want a crowd-pleasing starter, these crostini deliver serious flavor with a completely clean ingredient list.
