Sweet Potato & Avocado Bites

Switch the oven on to 200⁰C (Gas Mark 6). Put the oil and spices into a large mixing bowl, add a pinch of salt and a few grinds of pepper, then stir well to combine. Put the slices of sweet potato into the bowl and toss until they are all well coated with the spice mixture. Put the slices on to a large baking tray (or two smaller ones – they need to be in a single layer, with no overlap) and cook in the hot oven for 15 minutes, or until just tender to the point of a sharp knife.

While the slices cook, cut the avocado in half, carefully remove the stone and scoop the flesh into a mixing bowl. Grate the lime zest and add to the bowl, then cut the lime in half, juice one of the halves and add to the bowl, too. Sprinkle in a pinch of sea salt and use a fork to mash everything together. When the potatoes are cooked, arrange them on a serving platter or tray. Top each slice with a small dollop of smashed avocado, then garnish with sliced cherry tomatoes before serving.
