You have 2 choices:
1. Run the function corresponding to [tab] 3 times (by preloading the
keyboard buffer or by adding it to `minibuffer-setup-hook'.
This will make some extra displays and has built in delay.
2. Defining a simple function to display all possible completions
and adding it to `minibuffer-setup-hook'.
Here is the function and an example to the 2nd solution:
(defun minibuffer-all-completion ()
(with-output-to-temp-buffer "*Completions*"
(display-completion-list (all-completions ""
minibuffer-completion-table))))
;; An example.
(defun offer-some-choices ()
(interactive)
(let* ((minibuffer-setup-hook
(append minibuffer-setup-hook
'(minibuffer-all-completion))))
(completing-read "Select a name: "
'(("Klaus" . t) ("Klaus-2" . t) ("Klaus-3" . t)))
))
