It's been a long time since I cooked ham in the green beans,but it's a good combination and though it might be a good sandwich, my family loved it. I'm not a fan of ham. My brother-in law from South Carolina brought the country home back when he went for a visit,he said the spicy mustard cuts the saltiness of the ham and the 1000 Island dressing brings a slight sweetness.
Blanch green beans in boiling salted water for 1 minute. Remove and place in ice bath. In a hot skillet lightly saute beans in 2 T. butter, garlic salt and pepper. Remove and set aside. Spread spicy mustard on 1 slice of bread,1000 Island dressing on the other. Add cheese and ham on one slice of bread,sandwich together. Add butter to a warm skillet , add sandwich,brown on 1 side,turn over and brown on other side until cheese begins to melt. Remove from pan. Cut in sandwich in half. Garnish with pickle spears.
