The important thing about squash is to add flavors - especially spicy ones - otherwise it is too bland for my taste.
Lamb's lettuce is a typical salad of fall season and it has a great earthy taste. I only buy the German one because the French lettuce is planted in sandy ground and you can even wash it ten times and there will still be that grain of sand which you feel between your teeth at a certain point - a really nasty taste!
For the dressing I roasted red onions cut in dices, adding a spoonful of water and a teaspoon full of raspberry vinegar, give the dressing over the salad when it is still warm, add a sprinkle of lemon and a spoon full of olive oil.
The squash was cut into pieces, adding a chili and some sea salt, roasting it slowly in a pan, adding a little bit of water or white wine.
