Delicious sauce

I read a cooking magazine. I found a dish that looks so delicious and cooked it recently. It is fish saute with arranged sauce. Marvellous !! It is so simple, however so good.
I introduce the ingredients of the sauce.

1. soy sauce
2. olive oil
3. honey ( 1,2,3 = 1 large tsp)
4. wholegrain mustard (1 or 2 small tsp)

After fish is baked in a pan, put it out and take extra oils, put this sauce in a pan and heat a little. (Please be careful to not burn the sauce.) I think the sauce is OK for various dishes. It is say sauce based, however, is like western style sauce because of wholegrain mustard. Please try this sauce.
