salads don't require recipes! you just throw in pretty much what you have around, using some common sense: gherkins and olives may not go too well together. Start with the green stuff: use different lettuces, except for iceberg which is as nutricious as water and just as flavoursome. Add in any/all of the following: grated carrots, olives, chopped gherkins, pickled onions, various cheeses, chopped peppers -red for colour, mange tout, nuts, sunflower seeds, tuna fish or other tinned fish, apples, melon, tomatoes (also a fruit), avocado, fresh herbs, etc etc etc. (OK, maybe not all of the above!) This is your chance to empty the pantry of all those odd things that have been lurking at the back AND create new and interesting taste combinations to try out on your family!
Potato salad, greek salad, mozarella&tomato&basil salad.....be inventive, be brave! Dressings can be anything liquid-and-oily so that it sticks to the food - I've diluted pesto with a bit of olive oil and used that, or olive oil alone when I'm lazy
