Target did not have chili oil, so I just got some sort of chili sauce in the Asian food section (which is about ten feet wide; I really want to check the local demographics now that most of the #SoCal military bases closed). I added it to bottled spaghetti sauce and shell noodles (some made of whole wheat and some made of chickpea). Added "hot" Italian sausage (the generic Target brand) and ground turkey. (Tummy does not like large amounts of beef, so I tend to avoid it.)
I haven't tasted the resulting meal yet, but I expect it to be pretty good.
