Get a medium campfire going, or get your charcoal on the go. (If you’re making this on a stove, use medium high heat and a nonstick pan.)
Add the ground chicken and olive oil to a large cast iron skillet - or a dutch oven, and set over the fire or hot coals.
Cook - breaking up the meat as it cooks - just until it’s cooked though.
Add the chopped celery and onion, continue cooking until the just starting to become tender, another 2-3 minutes.
Note: If using frozen vegetables, you can thaw them first, or just add them in frozen. They’ll take a bit longer to cook if frozen, but it works just fine!
Add the remaining ingredients to the pan, stir well to combine. Allow to simmer for about 15 minutes, or until thickened to the texture you like.
Season with salt and pepper, to taste.
