Peel and dice your onion. Place half of it into your Airfryer along with the sausages on the grill pan and sprinkle them with salt and pepper and cook for 5 minutes on 180c/356f.
While the sausages and onion are having a head start place the rest of the onion inside the Instant Pot. Cook them on the sauté setting with a little olive oil and the garlic and cook until the onions are golden.
Add the mince to the Instant Pot and mix well and cook on the sauté setting for a further 10 minutes.
After 10 minutes give your sausages another 10 minutes at 180c/356f. At the same time dice your tomatoes, add all seasoning and give it a good mix. Cook for a further 10 minutes.
After 10 minutes add the tinned tomatoes, mix well and move to keep warm for 5 minutes as this will simmer the mince.
Drain the mince to remove any excess moisture and mix it with the soft cheese.
Place the sausages and onions over the hotdog buns, then the mince over it and then garnish it with more cheese and salad bits.
