Preheat oven to 180°C. Wash the spelt and cook it according to the instructions on the package. Wash the courgette and parboil them in salted boiling water for about ten minutes.
Drain the spelt, rinse with cold running water to stop the cooking, and transfer to a bowl. Add the pesto, Scarmorza cut into small cubes, and the diced cooked ham to the spelt.
Empty the courgettes and fill them with the spelt. Place them on an oven dish lined with baking paper, and drizzle some oil over them. Base in a hot oven for about 20 minutes. Remove from oven and serve immediately.
