I'm installing a 36" induction stovetop where a 42" gas stovetop was. This will leave a 3" gap on each side. Any ideas on how to make this look ok?

The counter is 23 3/4" deep and the new stovetop is only 21 3/8" deep, so there's also 2 3/8" of extra space at the back (or front) of the stovetop to fill.

Thanks!
