Prepare 30g of quinoa according to pack instructions and set aside (takes 12 – 15 minutes to cook). Drain 50g of black canned beans (you can use other beans if you prefer like red kidney, chickpeas, lentils) and mix with 80g cherry tomatoes, cut into quarters. Stir into the quinoa. Cut an avocado in half and remove stone. Scoop out flesh and lay on top of the quinoa. Mix together a teaspoon of extra virgin olive oil with a two teaspoons of lemon juice and a little black pepper. Drizzle over the salad and serve.
