Prepare the dressing: In a medium size bowl or container, combine vinegar, sugar, soy sauce and oil. Add the Turkey and onion and toss to combine. Cover and refrigerate for 1 hour or overnight. This helps the onions “pickle” removing the bitterness of the onions.
Prepare the noodle crunch: Preheat the oven to to 350℉. On a baking sheet, combine the noodles broken up into small pieces, with the almonds, sesame seeds and oil. Bake 10-12 minutes until golden brown. You can freeze these weeks in advance.
Before serving: Combine lettuce with tomatoes and Turkey/dressing. Top with ramen noodles crunch.
