Quick and easy to make this sandwich.
- Prep Time : 15 minutes
Spray a small frying pan with low calorie cooking spray and, using a chef's ring if you have one, fry the egg over a medium heat until cooked to your liking (you could poach the egg instead). Season and set aside.
Mix the quark, mustard and spring onion in a bowl, then season well and spread on to the bottom half of a roll.
Add the tomato, ham and egg.
Season well with black pepper and top with the lid of the roll.
