Snowed Under Colourful Garden Salad

It's not like we would've found any of these ingredients in the garden as yet, but "colourful greenhouse salad" just does not sound as appealing I suppose.

You need

• tender lettuce - any kind, really, apart from iceberg or bitter varieties
• half a cucumber, sliced
• half a red pepper
• 2 spring onion
• some fresh herbs, here: half parsley, half coriander

• half a shallot, very finely chopped, cover with
• lemon juice
• salt and brown sugar
• some pepper, then put
• a few drops of olive oil
• half a teaspoon of mustard
• cream
• yoghurt
• a pinch of nutmeg
