A Nice Fresh and Simple Salad That Takes Five Minutes

I went for a bike ride along Cross-Island Parkway, which is very close to my new place. Near the end of my ride I passed one of those little vegetable markets that are commonly found in NY (and maybe other cities, I don't know) and bought some items for dinner. Not much to it, really:

1/2 cup chopped fennel (leaf not seeds)
1/4 cup white onion, sliced
1/2 cup cucumbers
6 grape tomatoes
4 radishes, sliced
1 tbsp prepared Dijon mustard
1 tbsp rice wine vinegar
2 tbsp extra virgin olive oil
juice of half a lime
sea salt and black pepper, to taste
1 tsp dried tarragon leaves

Whisk the mustard, vinegar olive oil and lime juice together in a bowl. Add the vegetables and toss to combine.

Very simple and quick. You could add all sorts of things to it but I'd make sure to take out if you're doing that---the point is to be simple.
