Mama's Pickled Onions and Cucumber

In our house this was summer food. My childhood summers were full of BBQ with this on the table. I hate to admit it but if there were leftovers the next day I would butter some bread and put the onion and cucumbers on and eat with a smile on my face. I invite you to try my sandwich provided there are any leftovers. Mama (Carmen Jackson) didn't measure, but they were always wonderful. I am approximating in the ingredients so you may have to adjust things to suit yourself.
