Sous Vide Flank Steak Recipe with Tomatillo Salsa

Sous vide flank steak can be a great low cost meal. Flank steak is becoming more expensive as it increases in popularity but you can still find good deals on it sometimes.

I prefer my sous vide flank steak to have some bite to it so I normally cook it for 2 to 12 hours but some people prefer it to be meltingly tender and cook it for 1 to 2 days. The tomatillo salsa adds a nice tang to complement the beefiness of the flank steak while the corn adds a sweet undertone and a little crunch. This dish is complemented nicely by refried beans and yellow rice.
