Wash the zucchinis and tomatoes and let them dry.
Wash the rice and soak it for 15 minutes.
Core the zucchini, and cut the tomatoes into small pieces.
In a large mixing bowl, mix the diced tomatoes and minced garlic with the rice and spices.
Add olive oil, and blend them well.
Start stuffing them as much as possible but also leave ¼ inch of space by the opening.
Place them in a pot and lay them down.
Add water just enough to cover and then add the tomato sauce.
Add dried mint, olive oil, and salt, and mix.
Put the pot on medium to high heat until it boils. At this point, reduce to medium-low heat, and cover.
Let it simmer on a low bubble for 30-45 minutes. Once cooked, adjust for saltiness.
For the instant pot, just cook them the same way on high pressure for 10 minutes.
