Warm the oil in a casserole dish over a medium heat.
Add the onion, garlic, oregano and a pinch of pepper. Fry for 5 minutes until softened.
Add the sliced sausages. Fry for a further 5 minutes.
Add the tomatoes, beans and vegetables. Stir.
Put the lid on the casserole dish. Place in the oven for 45 minutes until rich and delicious.
Scatter with fresh parsley and serve.
If you have leftovers of your veggie sausage and bean casserole it should be stored in the fridge or freezer. Make sure to cool it completely and then put your leftovers into a suitable sealed container and into the fridge or freezer within 2 hours of cooking.
