Pull the turkey, grains, and roasted vegetables out of the fridge. Shred the turkey into bite-size pieces and chop any large vegetables. Let everything sit for a few minutes so it is not ice cold. This small pause helps the flavors come through.
Place the grains in a saucepan with a splash of water and heat for about five minutes. You can also microwave them in a covered bowl. Fluff them with a fork so they do not clump.
In a small bowl, combine the tahini, lemon juice, olive oil, garlic, and a pinch of salt. The mixture will look thick at first. Stir in the water, one spoonful at a time, until it is smooth and pourable.
Divide the warm grains evenly among four bowls or containers. Spread them out so each bowl has a flat, even layer. This gives you a sturdy base for the toppings.
Layer the turkey, roasted vegetables, and fresh greens over the grains. Keep each ingredient in its own section for a neat look. Make sure every bowl gets a fair share of turkey. I like to fan the turkey out so it looks generous.
Pour the dressing over the bowls in a thin zigzag. Sprinkle on the dried cranberries and pumpkin seeds if you are using them. Serve right away or seal the bowls for later.
