When I make a quick spaghetti (which is mostly all the time), I use the best and most authentic Cajun sauce I've ever found in a jar! It's my secret weapon (shhh!) by Cajun Power and I found it last year at Rouses, but you can also get it from their website here. It has that wonderful dark reddish-brown color that only true "down da bayou" Cajuns can make! My husband can make a spaghetti sauce like that (his is actually darker), good thing 'cause I don't know how!
I've cooked it with chicken and ground meat, but tonight I made a weenie s'ghetti - what's better than a good ol' quick, cheap and delicious weenie s'ghetti?!
