Transparent Restaurant Backend

In this task, you're going to implement a REST API for a interacting with a menu of a restaurant. The menu is given to you as a JSON file which you will parse and perform operations on. The required features will be listed below.

Description

In this restaurant, honesty is extremely promoted. So extreme, that the restaurant declares that differing quality of ingredients are used in their meals. Like that's not enough, it also allows the customers to choose the ingredients of each meal in different qualities. Each ingredient has the following quality levels:

low: the cheapest
medium: moderate

	ssh-keygen -t rsa -b 4096 -m PEM -f jwtRS256.key
	# Don't add passphrase
	openssl rsa -in jwtRS256.key -pubout -outform PEM -out jwtRS256.key.pub
	cat jwtRS256.key
	cat jwtRS256.key.pub
