Prep the veggies by chopping the onion, and mincing the garlic and jalapeño.
In a large skillet over medium-high heat, sear the stew meat on all sides. This should only take a couple of minutes, as the meat does not need to cook through.
Add all of the ingredients to a slow cooker, and stir to combine.
Cook on "high" for 4 hours, or "low" for 6 to 8 hours.
