Thanksgiving Leftovers: Onion Dip Turkey Reubens (aka Rachels)

In a large skillet, heat the oil, two turns of the pan, over medium-low to medium. Add the onions, garlic, and sugar; season with the salt, black pepper, white pepper, and thyme. Cook, stirring occasionally, until the onions are caramel in color, about 20 minutes. Stir in 1/4 cup water and stir to evaporate, 1 to 2 minutes. Remove from heat and stir in the sour cream.

Meanwhile, for the sandwiches, in a small pot, warm the sauerkraut and the caraway and cumin seeds over low heat just until heated through, about 5 minutes.

After the onions have cooked for about 15 minutes, heat a griddle or grill over medium. Lightly butter one side of each bread slice and build sandwiches by layering the mustard, half of the cheese, a little sauerkraut, the turkey, onion dip, and then the remaining cheese between the bread slices (buttered sides out). Cook until the bread is golden and the cheese melts, about 2 minutes per side. Cut in half. Serve with the pickles and chips.
