This is fantastic! I thought cinnamon and allspice sounded a little odd, but nope, the combination is spot on and this is a great dish. I'm going to put it in my "good enough for company" cookbook. It's super easy to make, but it has just enough pizazz that it looks like you fussed over it. Only one caution, the zucchini is a bit limp after cooking, so use two forks to lift it out of the pan without spilling. :-)
I missed the instruction in step 6 to cover this, so the rice on top our zuccs was a little crunchy-that didn't spoil the yummy flavours in there though. This is a great, simple recipe that I'll make again before my zucchini are finished in the garden.
