I have never worried about the water quality in the 3rd world, much to the surprise of one of my Cambodian moto guides who was astounded that I would accept to eat breakfast at a roadside camp when we were returning from Bantay Srei. In all of my travels, I have only got "the bug" in two places -- Staying with friends in Karachi where we only drank boiled water and a meal at the Yogyakarta airport before flying back to Europe. In the second case, my lower bowels completely solved the problem during the transit stop in Singapore.
The best thing about salad is that you can use just about anything and change the ingredients on a whim. Tonight I started with a few elements that needed using rapidly -- Belgian endive and fresh mushrooms. With that base, I added chopped onion, chopped parsley, chopped celery and charry tomatoes. My first thought was to top it with smoked herring but at the last minute, I opted for fried lardons. Therefore no need to use salt, but I ground some pepper on top and added olive oil, balsamic cream and a bit of lime juice. Came out to my complete satisfaction.
Tonight for dinner I made a salad of sliced red onion, red bell pepper, fresh fennel, a lot of chopped curly parsley and some whole wheat brown coquillettes (tiny elbow macaroni) seasoned (besides salt and pepper) with lime juice, olive oil and sesame oil.
