Mary has shared a plethora of traybake recipes throughout her career, including this sausage traybake shared with BBC Food. It has more than 150 five-star ratings, with even the chef herself claiming it'll become a "firm family favourite" once you make it.

Serving four to six people, the recipe notes said: "It can be cooked in one dish and is so quick and easy to put together. Choose your favourite type of local, British sausage for this recipe-my family loves leek and sage."

Ingredients:

• Two tablespoons of olive oil
• Two large onions, sliced lengthways into wedges
• Two red peppers, deseeded and diced
• Two garlic cloves, chopped
• One tablespoon of chopped fresh thyme leaves
• 500g baby new potatoes, halved
• 12 sausages, pricked with a fork
• 200ml white wine
• Salt and freshly ground black pepper

Method:

Start by preheating the oven to 220°C/220°C Fan before placing all of the ingredients except the wine in a large, resealable freezer bag.

Seal the bag and shake well to coat everything in the oil. Alternatively, place all the ingredients in a large bowl and toss them until they are fully coated.

Tip the ingredients into a large roasting tin, spreading them out into one even layer and ensuring that the sausages aren't covered by any of the vegetables. Season well with salt and pepper.

Roast for about 30 to 35 minutes, or until golden brown. Remove the sausages from the oven, then turn them over and toss the vegetables in the cooking juices.

Pour in the wine and return the dish to the oven for a further 20 minutes, or until the sausages are cooked through and the potatoes are tender and browned.

Serve hot, accompanied by a dollop of mustard on the side, if desired.
