Put a few frozen (or thawed) chicken breasts, half a jar of salsa, a third of a packet of taco seasoning, and a third of a packet of ranch seasoning into a slow cooker.
Cook on high for 3-4 hours or low for 4-6 until the chicken falls apart with a fork.
Shred it all together in the pot, then eat in tacos, nachos, tostadas, or whatever else.
