Lentil and Feta Salad

Day four of the "salad cleanse" and Dave tells me he's reached his goal weight. Whoa. I guess this plan of ours has really worked! Of course now he has a new goal which is getting a six pack and he's dragging me down (up ?) with him. He has deemed it the "six pact." I don't know that it will require a special diet since we already eat clean but I will update you on our progress if there is any.

Ingredients:
1 1/4 cups puy lentils (you can also buy precooked lentils at Trader Joes)
2 carrots, finely diced

2 celery sticks, finely diced
4 oz feta cheese
2 tbsp chopped parsley

Dressing:
3 tbsp white wine vinegar
2 tsp Dijon mustard
5 tbsp olive oil
salt and pepper

Directions:
Put the lentils in a saucepan, cover with cold water, and add a pinch of salt. Bring to a boil and cook for 20-25 minuts until just cooked but not mushy. Drain and refresh in cold water, then drain again and transfer to a large salad bowl.
Add the carrots and celery to the bowl with the lentils. Crumble in the feta and add the chopped parsley.
Make the dressing by beating the vinegar  mustard and oil. Add the dressing to the salad and stir to combien well. Season to taste with salt and pepper and serve immediately.
