what do you want to know?
The basic premise of a decent salad is a mix of textures and flavours, and a good dressing.
So, for example, tomorrow, I'll be doing a big salad for a BBQ (hahaha - in theory, not convinced with the current rain). I'll be using a bag of mixed leaves (soft) and some chopped lettuce for crunchier options - I think DH bought romaine but iceberg could work and it's a good cheap option to bulk things up. I'm also adding some fresh basil leaves (chopped) because I have them lying around. If doing for just me, I might add some chopped mint but DH has an irrational dislike of mint.
then I will add some cucumber - quarter slices - adds crunch and juiciness but not too big. As I have crunchy lettuce, I won't add any peppers but would if I was making a smaller salad and wanted to just use the soft lettuce leaves. Although I do like the almost entirely green of this salad but don't like green peppers so maybe not...
Then some avocado slices - creaminess, and flavour (feta is an excellent option as well or instead. Ditto goats cheese if you prefer).
As it's Easter, I'll chargrill some asparagus to add in as well - makes it more interesting, and seasonal. I note also that chargrilled slices of courgette or even aubergine work well too. Or tender stem broccoli.
then some toasted pine nuts and some thinly sliced spring onion for some alternative strong flavours.
The dressing will most likely be lemon juice, greek yoghurt, some olive oil, mustard, sprinkle of sugar (or a bit of honey), few mixed dried herbs, salt and pepper.
