Gather your mis en place; get together all of the equipment needed for the recipe and gather your ingredients.

Prepare the herbs by removing the leaves from the stem and discarding the stems.

Grate parmesan cheese.

Remove the peel from the garlic and chop roughly.

Cut the lemon in half, and squeeze out the juice, making sure to dispose of the seeds.

Measure out sunflower seeds and olive oil.

In the bowl of a food processor combine the herbs, sunflower seeds, garlic, parmesan, and a squeeze of lemon juice. Begin to blend.

While blending, drizzle in the olive oil to reach the desired consistency.

You can make your pesto as textured or smooth as you like. Season to taste with salt and pepper. If the pesto tastes flat, usually a pinch of salt and a squeeze of lemon is all it needs. Pulse to combine.
