Nachos with spicy beef chilli recipe. Nachos can be horrendously high in calories when they are piled up on a plate with melted cheese, guacamole and soured cream. We’ve made a lighter version by using cool tortilla chips (and less of them!) and topping them with a tasty low-fat chilli and reduced-fat cheese. This recipe serves 4 people so it’s ideal for entertaining and parties. By Shake It Up, Cambridge Weight Plan blog
