Heat a medium pan on a high heat. Add a few tablespoons olive oil.
Remove sausage skins and crumble the meat into chunks in the pan. Discard the skins. Fry, stirring occasionally for a few minutes, or until sausages are starting to brown on the outside.
Meanwhile chop capsicum (pepper) into long chunks and add to the pan. Halve tomatoes and add them as well.
Continue to stir fry for another few minutes or until the sausages are browned and cooked through and the tomatoes have started to break down and go a little squishy.
Season with salt, pepper and chilli and serve with baby spinach leaves scattered over the top.
