Pre-heat the oven to 220°C, Gas Mark 7.
Coat a baking tray with some oil.
Peel the plantains, making sure to chop both ends off, slicing the skin off.
Slice diagonally, about ½ inch thick.
Place in a bowl and season with some ground spice and salt, mixing thoroughly.
Transfer to the baking tray, leaving enough room between each slice.
Bake in the oven for 15-20 minutes, until golden brown.
Serve and Enjoy.
