In a large skillet heat sesame oil over medium heat, but don't let it smoke (sesame oil has a low smoke point so it can smoke easily, which you don't want).
Add shallots and cook stirring constantly for 30 seconds or so, then add ginger and continue to stir for 30 seconds. Add garlic and cook just 30 seconds longer removing from the heat if anything starts to burn.
Push shallots, ginger and garlic to the edges of the pan and add the turkey to middle of the pan where it is hotter. Let turkey cook, breaking it up with a wooden spoon for a minute or so, and then incorporate the shallots, ginger and garlic. Add the red pepper flakes. Continue to cook turkey until it is no longer pink and it is cooked through.
Add soy sauce, honey and sriracha to pan and continue to cook until the sauce thickens up and the turkey is coated with it. Add the vinegar and cook just 30 seconds or so. Season with more honey or soy sauce if necessary, and set aside.
Fill romaine heart with turkey mixture (doesn't have to be super hot) followed by the cucumbers and red peppers. Sprinkle with green onions, cilantro and peanuts. Enjoy right away.
