Peel, chop, and puree kiwi. Combine all marinating ingredients including pureed kiwi in a large bowl.
Add trimmed London broil steak to the marinating liquid. Cover and refrigerate for at least 4 hours.
After, either grill the beef or sear it on both sides on the stovetop then put it in the oven at 350°F for about 7-10 minutes. The longer the beef states in the oven the more done it is.

Chop all the fruits and veggies.
Combine and toss all into a medium size bowl. Cover and refrigerate for at least 4 hours along with marinating steak.
Top cold fruit salsa on the grilled steak and enjoy.
