Cook the vegetarian sausages according to the package's instructions, which usually involves pan-frying them in a bit of oil over medium heat until they're golden brown and thoroughly heated.

While the sausages are cooking, prepare the hashbrowns in a separate pan according to the package instructions, aiming for a crispy and golden brown exterior.

Warm the bread roll in the oven for a few minutes at 180°C (350°F, Gas Mark 4) if you prefer it toasted, or you can use it as is for a softer texture.

Once everything is cooked, slice the bread roll in half. On one half, layer the cooked vegetarian sausages.

Place the hashbrowns either on the side or on the roll with the sausages for a fuller sandwich.

If desired, you can add some condiments such as ketchup, mustard, or vegan mayonnaise to enhance the flavors.

Cover with the other half of the bread roll and serve hot for a satisfying vegetarian breakfast.
