These are Padron Peppers. They are extremely mild for those who have sensitive palates. I stay away from spicy foods, but I have to tell you that these are delicious. The majority are very sweet but once in a while you get a spicy one in the bunch. 

Just saute them in a little olive oil until they have softened. About 6-8 minutes. 

Season with salt and serve. They make a great snack. Enjoy!
