This is just a quick salad I made from an idea on the Running with Tweezers blog. Sweetcorn and tomato seems like an odd combination but it works really well. I swapped red wine vinegar for lemon juice because I wanted a fresher tang. I used tarragon here, but mint or basil would work just as well.
100g tomatoes, deseeded & chopped
1/2 red onion, finely chopped
1 tsp fresh tarragon, finely chopped
Juice of 1/2 a lemon
2 tbsp olive oil
Put the ingredients in a bowl, season with salt & pepper and mix thoroughly.
Leave to stand for half an hour at room temperature before serving.
Serves 1 as a light lunch, maybe with some nice cheese and a few crisp green leaves
