Heat 2 tbsp of olive oil in a medium sized sauce pan and sauté onion and all vegetables for 5-7 min until they start to soften.
Add garlic and herbs and season generously with salt and pepper. 1/2 tsp of each is what I like. Start there, and adjust to your tastes the next time you make this.
Add your meat and brown it, or if you prefer brown your meat first in a separate pan and then add it (I add it to the vegetables and brown it with them because I find it gets more flavour that way but either way is fine) and season with salt and pepper to taste.
Add the tomato paste and cook for a minute then add the wine if using and continue to sauté and stir until it has reduced.
Add diced/crushed tomatoes, rice and broth/water to the pan (add more if sauce gets too thick as needed) stir well, check and season with salt and pepper to taste and let simmer on medium low for 5-10 min until it’s a little thicker and the rice is almost cooked through. Stir in the cheese if using and then remove from heat and set aside.
Meanwhile clean and cut the tops off the peppers and remove seeds and ribs.
Preheat oven to 350F.
Prepare your pan or casserole dish. Pour the passata and water/broth onto the bottom of pan and then place the peppers into pan cut side up so that they are ready to stuff.
Stuff all the peppers & tomatoes. Feel free to overstuff them because even if they are overfilled it will just add to the sauce at the bottom of pan (if you have extra stuffing it makes a great lunch bowl so don’t stress if you have any left over).
Put the tops on the peppers and toss in the chopped potatoes around the peppers (if using potatoes).
Drizzle with remaining ¼ cup of olive oil over the peppers and season with salt and pepper.
Cover with lid or foil tightly and roast for 30-45 minutes depending on size of peppers.* Then increase temperature to 375°F, remove foil and continue cooking for another 20-30 minutes until edges are slightly charred, and peppers are softened and withered and you can cut through them easily with a knife.
Remove from oven, let cool for a few min and serve with some of the sauce at the bottom of the pan along with potatoes and serve with olives and feta on the side.
