Write a function that accepts a dictionary containing keys and values and returns a list of all "key-value" pairs. If a value is a nested dictionary, the function must recursively extract keys and values from it.

Example:

Input:
data = {'a': 1, 'b': {'c': 2, 'd': {'e': 3}}, 'f': 4}

Output:
[('a', 1), ('c', 2), ('e', 3), ('f', 4)]
