Whole wheat pasta with broccoli and walnut pesto

Wash the broccoli and separate it into florets and stems. Cut the florets into small pieces, and peel and dice the stems.

Bring water to a boil in a large pot, add salt, and bring to a rolling boil. Add the whole wheat spaghetti and cook according to package instructions (approximately 10 minutes).

While the pasta is cooking, prepare the pesto: put the peeled garlic, grated Parmesan, walnut kernels, olive oil, baby spinach, basil, lemon juice, diced broccoli stems, salt, pepper, and half of the broccoli florets into a blender. Blend until you get a homogeneous mixture and adjust the taste with salt and pepper.
