I got another of those yummy eye-of-round roasts (becoming a favorite) and stuck it in a bag with the olive oil/lemon/whatever marinade last night. Intentions of cooking it this evening (happy mom's day to meeee). Then my ex (of all things) invites me over for chicken fried steak for a mom's day treat (weirder things have happened). That is the one thing I can't make on the egg! So I said ok. Now question is..how long can I keep Senor Roast in that bag in the frig before it goes either toxic or just is gonna taste like hell? Can it make it till Monday night (soaking since Sat night) or should I cook him and just have cold roast sandwiches (with lots of horseradish..yum)?
