The beauty of this is that with the addition of a few ingredients, the flavours change. You start with your basic cheese roll, add a lick of mayonnaise, tomatoes and aromat for a cheese and tomato roll; salad cream, lettuce, tomato and aromat for a cheese salad roll or slices of onion for cheese and onion.

Ingredients
1 crusty roll or two slices of bread
7g butter
2 tsps salad cream or mayonnaise (optional)
25g cheese of your choice, grated
1 lettuce leaf (optional)
1 tomato, sliced (optional)
3 slices of onion
Aromat
Black pepper

Method
Slice the roll in half and butter.  Spread the salad cream on to the bottom of the roll and top with the cheese and then the tomatoes. 

Season the tomatoes with Aromat (or salt) and black pepper.  Top with the lettuce leaf, put the top of the bun on and slice in half.

Variation:
Remove the salad and just have cheese.

Cheese and onion: Add some fresh onion
