Prepare the vegetables: Grate the carrot, zucchini, and mushrooms. Finely dice the onion, you can choose to grate the onion if you prefer.
In a large pan heat the olive oil. Sauté the onion, grated carrot, and zucchini until softened and starting to go golden.
Add the tomato paste, sauté for 2-3 minutes this helps deepen the flavour.
Add the mince and the mushrooms, cook until the beef mince is browned.
Add the tinned tomatoes, dried herbs and spinach. If your kids are a little weary of green specks in their food please check out the tip section in this post as I have a great hack for that
Simmer for 25-30 mins until everything is well cooked, the sauce has thickened and flavourful. While the spag bol is simmering cook your chosen pasta as per the packet directions.
Serve with cooked pasta.
