Cut off the tip of the zucchini. Don't discard it since you will be using it to cover the zucchini when cooking.
Use the zucchini corer to make a hollow opening by removing the squash from the inside. Repeat the rest of the zucchini
Wash them with warm salt water to keep it firm. Set aside.
Making the Stuffing
Add olive oil in the pan. Once hot, add chopped red onion. Stir to combine till it turns translucent
Add the ground beef. Stir to mix for few minutes till the juices released by the meat will be fully evaporate
Add the soaked uncooked rice, allspice and coriander & dill leaves. Mix to combine for few minutes
Add salt and black pepper for taste. Once done, set aside.
Preparing the Tomato Sauce
In a large bowl, add the tomato paste, warm water, cumin, grated garlic, salt and black pepper.
Use a wooden spoon to stir to combine till it is fully dissolved. No need to boil or heat it yet since it will be done after stuffing the zucchini. Set aside.
Stuffing the Zucchini
Use the spoon to fill up the inside of the zucchini with rice stuffing mixtures.
Make sure there is at least 1 inch space between the top and the filling to allow the rice to expand when cooking.
Use the stalk or the grape leaves to cover the zucchini. Repeat the rest
Cooking the Kousa
Add the grape leaves, chopped tomatoes and chicken breast on the bottom of the pressure cooker
Add the stuffed zucchini, and then again the grape leaves followed by the sliced potatoes.
Pour the tomato broth into the pressure cooker. Before turning on the fire, cover with the lid and close it properly.
Once it started to boil, place the valve on the pressure cooker. Starting timing for 20 minutes once you heard the hissing sounds from the valve.
When done, carefully remove the valve and wait till no more hissing sounds and the steam. That is when it is safe to open the lid.
Transfer the cooked stuffed zucchini into plate together with potatoes and chicken. Include pouring the tomato sauce on the plate as well.
Serve with Arabic salad, plain yogurt and pita bread.
Notes
Soaked the rice for 30 minutes to help reduce the excess starch. In this recipe, I am using a Black Beauty Zucchini since I can't find Magda or Mexican Grey Squash.Instead of tomato paste, you can use canned tomatoes or fresh tomatoes.If you are confused with the instruction, look at the step-by-step pictures shown on the post. If you are using an ordinary cooking pot, cook it on low heat for 1 hour.
