Lay capers out on a paper towel and pat dry. Then add some flour to a shallow bowland add capers. Make sure they are full coated. Remove from flour and put on a plate. This helps get some of that excess flour off of them before you fry.
Add oil to a pan until there is enough for the capers to be fully submerged. Once oil is hot, add capers. Cook until capers start to brown on the edges, about 2-3 min. Remove and add to a paper towel again to collect some of that excess oil.
In a bowl, combine the sauce ingredients.
Slice zucchinis thinly and lay out on a plate.Since you aren’t cooking them, slicing them thin lets them really absorb the sauce.
Right before you're going to eat them, add sauce, crushed pistachios, fried capers, and shaved parm. Enjoy!
