Ingredients 
for the stuffing
1 small onion, peeled, shredded
1/3 packed cup chopped parsley
1/3 packed cup chopped dill
1 14.5 oz canned diced tomato
1/2 cup water
2 tbsp extra virgin olive oil
Scant 1 tsp allspice
Scant 1 tsp garlic powder
Salt and pepper
4 large and very firm tomatoes, divided (3 to be cored and stuffed, 1 to be sliced)
1 small onion, sliced into rounds
2 1/2 lb Medium-sized zucchini, lightly peeled
1 can tomato sauce
3/4 cup water
instructions
In a large bowl, combine the stuffing ingredients fresh parsley, dill, diced tomatoes, water, olive oil and spices. Mix by hand to combine.
Now, remove the top of the remaining 3 tomatoes and remove the core to hollow out the tomatoes making room for the stuffing. Do this using a corer.
With a knife, remove the very top of the zucchini, then cut each zucchini in half to make shorter zucchini for stuffing. Now you need to hollow out the zucchini to make room for the stuffing.
Insert your corer about 3/4 of the way into the zucchini, making sure not to poke the bottoms. Twist the corer and pull out the zucchini cores or hearts. Do this a few times, and gently scrape the sides of the zucchini until you have hollowed each out making room for the stuffing. You’ll want to leave about 1/4 inch rim of zucchini.
Lightly oil the bottom of a large deep cooking pan like this one. Slice the remaining tomato and spread over the bottom of the pan. Now add the onion slices and the cores or hearts of the zucchini. Sprinkle with a little salt and pepper.
Loosely stuff the zucchini with the stuffing about 3/4 of the way (do not over-stuff or crowd the stuffing in the zucchini or it will not cook well).
Arrange the stuffed tomatoes in the center of the cooking pan, then add the stuffed zucchini (stuffed side up) around them. Tilt the zucchini a little, this helps them cook nicely through using less liquid.
Now add the tomato sauce and water. Sprinkle lightly with salt and pepper.
Place the pan on the stove and cook on medium-high heat until the liquid starts boiling. Turn the heat down, cover and simmer for for 50 minutes until the zucchini is tender and the rice stuffing is fully cooked.
Transfer to a serving platter or individual bowls. Top with the sauce from the cooking pan. Enjoy!
