Baked Spaghetti

Baked Spaghetti are made with leftover spaghetti, vegan chicken bites, olives and bell pepper. It is a spaghetti recipe that comes together in under 25 minutes, but will taste like it comes from an amazing restaurant. I made this quite often, because you can make it in advance and it freezes well for an easy weeknight dinner in no time.
