Step 1Combine mayonnaise, chili sauce and pickle relish. Spread dressing on each slice bread.
Step 2Top each of 2 slices bread with 1 1/2 ounces turkey pastrami, 1/3 cup sauerkraut and 1/2 slice Swiss cheese. Cover each with 1 slice bread to make sandwich. Spray top bread slices with cooking spray. Put sandwiches, sprayed side down, in preheated skillet sprayed with cooking spray. Cook over medium-low heat until bread is golden brown, 5 to 6 minutes, then turn to brown other side.
Step 3Cut sandwiches into thirds and serve with dill pickles.
