Rick, I'm sure that Fresh and Easy® has a wonderful Tiramisu made from scratch in their commissary!
But you'd have to forego the luxury of freshly laid raw eggs.

I may prepare the custard in a bain marie when I make it for guests because a lot of folks freak out over undercooked food these days.
Tiramisu is stupidly easy to make once you round up the ingredients. The mascarpone cheese was the hardest to source and I probably will use a substitute next time.

Good coffee, good weed, and time on my hands...
