Assuming you're after the recipe Ummm and not my supper (which aint gonna happen!) here you are....
Fry sliced streaky smoked bacon in olive until beginning to brown and crisp.
Add sliced leeks and fry for a couple minutes, season with black pepper add a good glug of sherry and bung a lid on. Steam until leeks are just tender but still have some bite.
Take off lid and add some cream bring to a simmer and add chopped tarragon, check seasoning and serve.
If you've got half a pot of philly, ricotta or whatever you can add that and adjust the amount of cream. A small handful of finely grated parmesan gives a bit more depth to the flavour. If you want a low fat option creme fraiche can be used but be very careful when simmering as it can easily split.
