Hi KP,
If you google Keto plans, you'll find so many you'll be spoilt for choice. :)
Here is an example from Prof Tim Noaks.
His green, orange and red list are very easy to understand.
Green=eat what you want, no need to count
Orange=be careful, keep an eye on portion
Red=avoid
Here is another menu sample from Dr Colin Champ.
Some more keto plans here.
My suggestion is to stock up on olive oil, goose fat, beef drippings, lard, butter and cream (if you tolerate it), coconut oil, coconut cream, avocadoes, and olives.
Cooking with and eating fat will be the hardest part to get adjusted to, if are used to low cal.
Goose fat is fairly neutral you'll not notice it with poultry, fish or lamb; lard is your classic bacony taste; drippings are lovely with beef and game.
Avocado are gorgeous and versatile, easily turned into sauces and dips -hot or cold. Olives are a staple snack: I swear they don't have calories! 
I cook meat and fish in the animal fats at medium to low heat and dress vegetables with raw olive oil or rich sauces (hollandaise, pesto, avocado...).
You'll soon get used to the veg, because they taste delicious when dressed with oil or sauces, or fried in butter or roasted in fat, with spices and herbs, with bacon and nuts..... 
If you stuck for ideas, there a few recipes on here; the ones I post are keto. (exceptions Xmas sweet menu!)
There are also lots of delicious recipes on Bootcamp.
