De-seed jalapeno and chop in large pieces. Place in blender.
Tear off tops of cilantro bunch, leaving stems, and add to blender.
Pour cans of tomatoes into the blender.
Cut the lime in half and juice both sides into the blender.
Add garlic and seasonings to the blender.
Pulse blender until jalapeno and cilantro is chopped. Continue blending until desired texture - chunky or smooth.
Taste for seasoning and stir to make sure all your cilantro and jalapenos are mixed up.
I like to make this a day or a few hours ahead so it can sit in the refrigerator and season and get good and cold!
Store in the refrigerator for up to one week. Watch the cilantro if are not eating immediately.
