A baby gem lettuce can be enlivened by decorating it with small mandolinned slices of fennel, radish, carrot and asparagus and adorned further with olive pieces and fresh peas. Carefully insert the slices into slots made into the lettuce with a knife.
For the lemon Vinaigrette
1/2 tsp finely grated lemon zest
2 tbs freshly squeezed lemon juice
1 tsp sugar
1/2 tsp Dijon mustard
a pinch of sea salt
4 tbsp extra-virgin olive oil
Freshly ground black pepper
Combine all the ingredients and whisk until the sugar has dissolved. This can keep in an airtight container for a few days.
