Clean the tomatillos and cut in half, do the same with jalapeno and remove the seeds if you don't like too much heat (I left mine in so the dressing was nice and spicy)). Broil for 5-10 minutes until slightly charred.
Put all the ingredients into a food processor or blender and blend until completely smooth, about 1 minute.
Notes
Serve on salads, tacos, or burrito bowls. I love this on top of roasted veggies too or as a chip dip. We basically love it with anything!
