Combine butter, wine, garlic, lemon juice and salt in a microwave safe bowl and microwave until warm, 45-60 seconds.
Using a kitchen shears, cut through the lobster shell in a line all the way to, but not through, the flipper bit at the end.
Pull the meat from underneath the shell and lay on top of the shell (this is easier to watch, there are several good tutorials on YouTube, search 'lobster tails').
Heat a broiler to high; brush lobster tails very generously with butter mix; cook until just slightly less than completely opaque, 5-8 minutes depending on the lobster size, until lobster meat is tender.
Sprinkle with parsley and serve immediately with the lemon wedges and the leftover warm butter mixture as dipping sauce.
