Jamie Oliver shows us how to boost our meals with color and nutrients; he cooks sustainable meatballs, a colorful chopped salad and a jelly dessert full of berries and elderflower bubbles.

Jamie celebrates the ingredients that can help our brains function and keep us energised, with a salmon traybake, harissa chickpeas, chicken balls in a vegetable broth and spinach and lentil fritters.

Jamie makes an easy and nutritious seared tuna and celebrates fibre-packed overnight oats.
