This is a basic but useful vinaigrette which is handy for livening up salads.
2 tbsp olive oil
Put all the ingredients together in a mug and whisk well with a fork. That's it!
Delicious served over a salad of chopped tomatoes, cucumber and red onion. Posh up with snipped chives, crushed garlic and a touch of mustard, and toss with cold new potatoes. Yum!
