Sweet & sour apple salad

Summer is starting here in US & I'm craving for some cool dishes rather than normal ones. You can enjoy it on any part of the day & to me it's for dinner... :)
I had some apples hanging around in my refrigerator & wanted to put them on a good use. I mixed lettuce with apples & believe me it's a sweet combination. 

Ingredients
1 Apple 
1/2 Lettuce
For sauce 
1 Tbs non-fat yogurt 
2 Tbs non-fat milk 
1 Tbs lemon juice
1/2 Tsp sugar
1 Tsp pepper powder
Pinch of salt 

Chop apple & lettuce. Keep them aside. Take a bowl & mix all the sauce ingredients in it.

Take a bowl & place a layer of lettuce & add apple on to of it. Pour some sauce on them & top it with some more lettuce. 

Finally mix them smoothly in the bowl & salad is ready to serve. 

Serve it chilled & it tastes awesome.. :)
