Label two gallon-sized freezer bags (I find that it's easier to label the bags before they have food in them!)
Prepare ingredients (rinse the chicken, mince the garlic, juice and zest the limes) and split all ingredients (except cilantro) into two gallon-sized freezer bags. Each bag makes about 6-8 servings, so this will make two meals.
Wash the cilantro and remove the leaves from the stems. Place the cilantro leaves into two smaller freezer bags and place inside the larger bag (or tape to the outside).
Lay the bags flat, squeeze out as much excess air as possible, and place in freezer.
The day before you plan to cook the meal, take out the freezer bags to thaw.
On cooking day, put the contents of one larger freezer bag (everything minus the cilantro) into slow cooker and cook on low for 6-8 hours or on high for 3-4 hours.
Add cilantro in the last 30 minutes of cooking time.
Serve with rice or cauli-rice, and add a large salad or cooked vegetables. These can also be served in taco shells with salsa, sour cream, shredded lettuce, shredded cheese, and guacamole.
