Single turn with minimum leakage inductance on a torroid.

I'm working ona a design around a zp42915-tc ferite torroid and a switching
supply.

One of the secondaries only requires a single turn. With bobbin would
transformer I'd spec out a turn of foil wide enough to utilize the entire
width of the bobbin. never did this for a torroid. How do I wind this to
minimize leakage inductance?

switch freq is 150K, full bridge topology.
