Mouth watering thread!
I love a lentil salad, ones with some bite, green or puy. Dress while still warm with LOTS of olive oil, lemon, salt, pepper, herbs (mint, corriander, chives, what ever's to hand). That's a base, add chilli, roast toms, feta, olives, etc as the mood takes you!
Courgette...thinly slice courgettes length ways and griddle. While warm toss in lemon, basil, olive oil, touch of garlic, mint, toasted pine nuts if you can be a**ed. Feta's a nice addition if you want protein.
I love thai style salads too. Cold noodles dressed with tamari, sesame oil, lime, corriander, and thinly sliced salad veg, eg, Q, carrots, pepper, bean sprouts...no need to slice those! Etc. Fried tofu and / or peanuts. Apologies to anyone thai for insulting your food culture with this over simplified thing.
