Cooked prawns are convenient, but can’t be reheated or they end up rubbery and unappetising. So what can you make with cooked prawns other than a prawn cocktail? These easy prawn crostini are the answer. They’re perfect finger food for a party and the recipe can easily be multiplied to feed a crowd. They look luxurious and generous, especially if you make your own mayonnaise, yet are super easy to make. The prawns are already cooked and everything can be prepared ahead of time for a quick assembly just before serving. Crostini can be made a few days ahead and stored in an airtight container. I use the smaller leaves from a baby cos lettuce, but you can trim down larger leaves if need be. The lettuce prevents the moist prawn mixture from softening the crostini, so they can be assembled half an hour or so before serving. I like a mixture of about half dill and half chives, but you can use parsley, coriander, chervil or French tarragon as well as or instead if you prefer. If you have gluten-free guests, just serve the prawn mixture piled into lettuce leaves. To turn these prawn crostini into a smart dinner party starter, make prawn bruschetta instead. If you prefer to start with green (raw) prawns, see the video below for tips on how to boil and store prawns.

We made the pot-sticker dumplings and bang bang chicken from the Chinese class the other night. Once again both exceeded our expectations. My husband keeps saying it’s better than going out to restaurants as the recipes and quality are amazing.

I find your weekly check-in to my kitchen an inspiration with chatty, warm, inspiring dishes to experience. Recently I was looking for a recipe for Persian spice blend advieh and yours was the first to catch my attention, even before I knew it was written by you. What a fun surprise to see your happy, calming face with a new friend sharing the benefits of Persian cooking.

Food, wine and travel! Three of my favourite things! Be Inspired with Roberta has been a wonderful experience and given me more confidence in the kitchen. I have learnt so much, cooked things I never would have attempted without Roberta’s excellent videos, and used ingredients I have never tried before.

I'm a competent cook whose learned so much from Roberta's online cooking classes. The recipes are yummy and Roberta’s video guidance offers so many little tips to improve flavour and organise the flow of preparation. I enjoy her warmth, sense of humour, and ability to giggle at herself when she occasionally messes up.
