the 2 i most often make are a shallot vinaigrette and and asian one. for the shallot one, i mince up a shallot and then put into a bowl and add 2 Tbsp vinegar and a little salt, and let that sit for about 10-15 minutes. then add 1 tsp dijon mustard and slowly whisk in about 6 Tbsp olive oil. add s+p to taste. i can't remember the amounts offhand for the asian one but it has minced garlic and ginger, rice vinegar, soy sauce, sake or mirin (or both), a little sesame oil, and olive oil. usually you want the vinegar:oil ratio to be about 1:3 or at least 1:2. i always toss the salad with the dressing before eating/serving it.
