Bring about 2cm (1in) salted water to the boil in a large saucepan. Chop broccoli into bite sized florettes and finely slice the stems. Pop broccolini in the boiling water. Cover and set your timer for 5 minutes.
While the broccoli is cooking, warm olive oil in a small frying pan on a medium high heat. Add garlic and chopped anchovy (if using) and cook for about 30 seconds before adding walnuts. Continue to cook, stirring for 3-5 minutes or until walnuts are toasted and everything smells divine.
When the broccoli timer goes, taste a piece to make sure it’s no longer crunchy. When you’re happy that its cooked, drain broccoli well. Return to the pan. Toss in the tuna (or other protein) and the anchovy crumbs (keeping a few to sprinkle over the top when you serve).
Divide between two bowls and top with the extra crumbs. Serve with salt at the table but you probably won’t need it.
