You can make this with any Bell or large pepper.
I like to use the Poblanos because they have lots of flavor and a little heat.
I roasted some Organic Carrots and Parsnips in the oven at 400 with some olive oil and greek Oregano.
I made some rice with a mix of red himalayan and some organic brown short grain.
I stuffed the steamed peppers with
Chopped roasted carrots and parsnips.
Rice - should not be more than 20% of the mix.
Chopped garlic and chopped fresh red or yellow peppers.
Roast for 30 mins or so or until the peppers are soft enough to be cut with a fork.
Here are a few options of what could be added.
Softened nuts, chopped almonds. Rasins. Onions.
If you want it to add meat. I suggest Chirzo.
