Italian Stuffed Pork Tenderloin

large pork tenderloin (Trish suggested getting the large pork tenderloin from Costco, so that it what we got-- if you can't find a large pork tenderloin, a regular pork loin also works)

jar roasted red peppers

pkg bacon (cooked, crumbled)

pkgs. dried pesto seasoning (like Knorr brand, can be found by the gravy/dressing mixes)

Spinach leaves (fresh (to taste))
