The combination of all four words together does seem rather bad. However, the words "chocolate" and "powder" are okay together. Check out these example sentences that use them together:

• My mom serves chocolate-chip brownies with powdered sugar on top.
• To make a good chocolate ice cream, blend together 2 cups of milk, 1 cup of cocoa powder, and 3/4 cup of sugar in a blender until aerated, then freeze in an ice-cream freezer.

See? Those words go fine together, if you do it right. HTH.HAND.

Come to think of it, I'm pretty sure the word "soy" is the main problem in the previous combination. The word "soy" should generally occur in the context of stir-fry or wok cooking and is usually followed by the word "sauce", although this may be omitted if it is implied by context. It should not occur in combination with the word "burger" or the phrase "La Choy".
