sometimes i will use rice vinegar or wine vinegar or lime juice in place of the lemon. whichever acidic element you choose will be fine.
instead of the vegetable oil, you can add regular or extra virgin olive oil. i have also tried it successfully with both grapeseed oil & even walnut oil.
one variation is to add a tablespoon of finely grated onion with its juice and 1/2 - 1 tsp of poppy seeds. another option is to add some hot sauce to it or minced fresh herbs and garlic. it's all up to you.
here is the basic dressing —
1-2-3-4 salad dressing
makes approximately 1/2 c.
1 tsp salt
2 tbsp sugar
3 tbsp lemon juice, freshly squeezed
4 tbsp vegetable oil
put everything in a small jar, seal and shake.
one of my favourite lazy day "all-i-can-manage-is-iceberg" salads for this dressing is just shredded iceberg lettuce, zesty croutons, some dried cranberries (craisins) and a small handful of roasted cashews.
