Preheat your oven to 350°F (175°C). Grease a loaf pan.
In a large bowl, whisk together the flour, baking soda, salt, cinnamon, nutmeg, ginger, and cloves.
In another bowl, mix the pumpkin puree, vegetable oil, eggs, sugar, and vanilla extract until smooth.
Gradually add the wet ingredients to the dry ingredients, stirring until just combined.
Fold in the dried cranberries, chopped nuts, and mixed seeds.
Pour the batter into the prepared loaf pan and smooth the top.
Bake for 60 minutes, or until a toothpick inserted into the center comes out clean.
Let the loaf cool in the pan for 10 minutes, then transfer to a wire rack to cool completely.
