Toasted cheese sandwich

I no longer eat butter and dislike margarine, so if I want to make a toasted sandwich these days, I tend to fry it in a minimum of olive oil.  However, so far I've been unable to find edible vegan cheese in New Zealand, so, sadly, toasted cheese sandwiches now exist only in my memory.  

I'm still looking for a successful vegan "Cheddar cheese" recipe.  All suggestions gratefully received.

Makes one

2 slices bread

butter

Cheddar cheese or similar

• Butter the bread generously.
• Slice the cheese and fit it to the bread – don’t make the sandwich too lumpy or it will be difficult to toast and don’t let the cheese overlap the crusts because it will drip onto the toaster and start to burn.(This is much less of an issue if you 'toast' it in the frying pan) 
• Put the toaster over a medium flame and carefully place the sandwich on it. Don’t use too high a flame or the bread will toast before the cheese has started to melt. Depending on the size of both your bread and the flame, you may have to move it around to toast evenly. 
• When one side is done turn it over and toast the other side.

Variations:

• Cheese and mustard: make as above, substituting Dijon or your preferred mustard for the butter. If you don’t watch calories, you can use butter and spread the mustard on the cheese.
• Cheese and onion: add thin slices of onion with the cheese.
• Fried egg sandwiches are good at any time of the day, although this isn’t strictly a toasted sandwich.
• Peanut butter is good, and even better with a couple of slices of tomato.  Beware that the tomato can get extremely hot.
  
• Make them with banana skin bacon. Toast the bread on one side only and if you’re feeling particularly decadent, dip the untoasted side in the cooking oil before assembling the sandwich.  
• Any bean or nut spread will go well on a toasty.  This can also get extremely hot.
