Add the potatoes and toss to coat in the fat. Add the salt, oregano and smoked paprika and toss well again.
Bake for 30 minutes or until they are starting to crisp up.
Meanwhile, slice the spring onions and chop the tomatoes. Grate the parmesan.

Once the potatoes are ready, top with the almonds, spring onion, parmesan and feta and pop back in the oven for another 5-10minutes.
