In a large bowl, mix together the flaked almonds, rolled oats, sunflower seeds and chopped walnuts.
In a small bowl, stir together the mustard, olive oil, salt, pepper, garlic, smoked paprika powder and onion powder until smooth. Add to the dry ingredients and mix well with a spoon.
Place the mixture on a baking paper-lined baking sheet and distribute it evenly. Bake for about 20 minutes until the granola is browned. After 15 minutes, check whether it is browning evenly and turn with a spoon if necessary. Take out and let cool.

The granola will keep fresh for about 3–4 weeks in an airtight container.
