Peel the pumpkin if you need to and cut it into small cubes. Boil in salted water for approx. 10 minutes. Strain and blend until you've got a smooth pumpkin purée.
Dissolve yeast in water and combine with flour for a minute. Add pumpkin purée, salt and olive oil and knead the dough until it's very smooth. Cover with plastic wrap or a kitchen towel and let it rest for 1 hour at room temperature.
Put the dough on a baking paper or in a mini baking mold. Pour some olive oil on top of the focaccia and press your fingers into it so that you create holes. Preheat the oven to 230 °C. Bake the focaccia for 20-30 minutes.
