My Sautéed Peppers and Onions are the side dish that will become your go-to when time is short. Sautéing is one of my favourite methods of cooking vegetables. It is quick, easy and produces vegetables that maintain their colour and flavour, whilst becoming lightly caramelised and the perfect degree of tender. Peppers and onions are perfect for this cooking method as they highlight their natural sweetness and flavour.

Ingredients and Substitutions:
Please see the recipe card further along in the post for exact quantities of ingredients and the full method.
- Red bell peppers/capsicums – I use red peppers as they are beautiful and sweet. You could also use some yellow peppers for a great colour contrast.
- Brown/yellow onions – these are the onions most often used in cooking, but you can use white or red onions if you prefer.
- Extra virgin olive oil – for the best flavour, use the best olive oil that you have.
- Garlic – my preference is to use fresh garlic cloves. Their flavour is superior to prepared garlic.
- Balsamic vinegar – richly flavoured and the perfect complement to the sweet peppers and onions.
- Chilli flakes, sea salt and freshly ground black pepper – for seasoning the dish.
- Fresh basil – for garnishing the dish.
Variations:
Herbs – dried oregano, fresh rosemary or parsley can also be used.
