Question:
If -for whatever reason I have not worn tefilin at shachris and plan on putting on tefilin later (with or without mincha) am I allowed to eat before being mekayim the mitzvah of tefillin that day?
Answer:
Hello,
Before addressing your question we should not push off putting the tefillin on for later in the day, rather they should be put on as early as possible. Regarding eating before wearing them, after davening shacharis, you may eat a snack, but not a bread meal, and not cake or cookies more than an eggs worth.
Best wishes
