Prepare papaya by peeling the skin off, cutting in half length-wise, and scooping out all the seeds. Using a mandolin, shredder, or food processor with shredding attachment, cut papaya into very thin julienne slices approximately 3-inches in length. Set aside.
Using mortar and pestle or food processor, grind together dried shrimp, garlic, red chili flake, fish sauce, sugar, and lime juice.
Place shredded papaya into a large mixing bowl. Pour sauce mixture into papaya salad and mix into papaya salad. Wearing gloves, use hands to squeeze papaya and pound it with your fist. This will help to enhance absorption of flavor and sauce.
Then add in green beans and cherry tomatoes and continue to squeeze and pound until all tomatoes are slightly crushed.
Serve a portion onto a plate and top with roasted peanuts. (Only put peanuts onto the specific portions you plan on eating.)
