Dear Zucchini

Dear Zucchini (and onion) --

I do not have the patience to wait for you to release your liquid. I know the recipe says to turn down the heat so that you cook without browning, but what progress does that show? Obviously browning is a sign of cooking progress. If there is no browning, how am I to tell if there is any progress being made? This seems like a cruel trick... if I just turn up the heat won't everything just finish sooner?
