Cook the pasta in plenty of boiling water and drain.
In a pot, heat the olive oil and whisk in flour. Whip in the boiling water, sea salt, garlic powder and turmeric. Then whip in the yeast (large flakes are best).
Mix most of the topping with the macaroni in a bowl. Place the mixture in a casserole and top with the remaining creamy sauce. Sprinkle with paprika. Bake at 15 minutes at 180C/350F in a pre-heated oven.
Broil 2 minutes to brown the top after baking.
