Pre heat your oven to 200C and add your sausages to a large baking dish to start cooking. Bake in the oven for around 10 minutes. Meanwhile put your potatoes on to boil and par boil for 10 minutes.
Add the par boiled potatoes to the tray with the sausages alongside the carrot, onion, garlic and cherry tomatoes. Dollop over the red pesto, drizzle over a little olive oil and sprinkle over the dried herbs, salt and pepper.
Bake in the oven for around 40 minutes - stirring half way through, I like to wait until the potatoes are nice and crispy and the sausages are browned.
