My fast work lunch is a bowl of prawns (bought from tescos on the way in), mixed with lemon juice, a chopped spring onion, chopped coriander, a sprinkle of paprika and zapped in the microwave for a minute.
On PV days I do the same thing with cooked chicken and ready chopped stirfry veg (again, from tescos)
The takeaway eaters always look on with envy!
I sometimes snack mid afternoon on greek yogurt with a tablespoon of muller toffee spooned on top, or, on PV days, a bag of cherry tomatoes.
