Once you have all of your veggies ready, you can start cooking: in your frying pan, place onion, garlic & all of the peppers with a good tablespoon of avocado oil and let them cook, frequently stirring as you would want to avoid adding any other liquid. If absolutely necessary, add some white wine but just enough so that the veggies don’t stick to the pan, you don’t want to have a broth forming. Let your veggies cook with lid on and keeping an eye on them.
