I'm veggie, I don't eat fish, and much prefer a salad to a sandwich when I'm out and about. I've had some salads from M&S a few times, and they've been delicious. The ones I've had have been the Fuller Longer one, with beans and quinoa and feta; and a similar one with goat's cheese and quinoa. Both have lovely dressings in a pot. I've also had something similar from Waitrose.
How can I recreate these at home? Is there any recipe book for substantial veggie salads (I mean not leaves!)
