Slice avocados and nectarines into approximately the same size pieces and lay equal amounts on each plate.
Drain (but do not completely dry!) fresh mozzarella and add to each plate.
Finish with a drizzle of aged balsamic reduction, basil, sea salt, and a generous amount of fresh cracked black pepper.
We found that when plating these, the messier, the better. When we tried to line up the slices, it looked all wrong. This is a super casual meal. Don't overthink it!
