Ingredients (Serves 6)
For the Caesar dressing
Grill or fry the bacon for 2-3 minutes until crisp. Leave to cool then cut into thin strips. Roughly shred the chicken into large strips.
To make the dressing, put the egg yolk in a bowl, add the lemon juice, Worcestershire sauce and a little salt and ground black pepper and whisk until frothy. Whisk in the oil gradually, until thickened and glossy. Add 2 tbsp water to thin the sauce. Stir in the cheese.
Lay 1 tortilla flat on a work surface and arrange a little lettuce down the middle of it. Top with chicken, bacon, anchovies, a spoonful of the dressing and, finally, more lettuce. Wrap the tortilla into a roll. Wrap the roll in a piece of greaseproof paper, tucking in one end as you roll. Repeat to make 6 wraps. Chill in the fridge to serve later.
