For the dressing, whisk the juice of 1 large lemon, ⅓ cup of extra virgin olive oil, 1 teaspoon of dried dill, and 1 minced garlic clove. Season with salt and pepper.
Cook 2 cups of pearl couscous in 3 cups of boiling water until tender. Drain off any remaining water and let cool.

Add 425g of canned chickpeas and 400g of canned artichoke hearts, both drained, then 15 fresh basil leaves and the dressing. Toss gently.
