With potato masher, in medium-sized bowl, mash chickpeas. Finely chop capers and add to bowl along with green onions, cilantro, and mint.

In separate bowl, combine yogurt, Dijon mustard, tahini, turmeric, and paprika to make dressing. Pour over chickpea mixture and stir well. Taste for seasoning and add salt, if required.

To assemble sandwiches, lay out 2 pieces of bread and cover each with a thin layer of chickpea mixture. Sprinkle about 1 Tbsp pumpkin seeds on 1 slice of bread and top with about 1/4 cup sunflower sprouts. Sandwich the 2 pieces of bread together, pressing down lightly. Repeat with remaining bread to make 4 sandwiches. Cut each lengthwise into 1 inch tea sandwiches.
