In a large glass pyrex dish, combine the mirin, balsamic, agave, soy sauce and olive oil. Place the very-well pressed tofu into the dish, flip over once and place into the refrigerator to marinate for a few hours.
When you are ready to prepare the dish, place the couscous, broth or water, salt and Earth Balance into a small saucepan. Bring to a boil, then reduce the heat and cover. Stir it every five minutes or so.
In a a separate skillet, heat the olive oil over medium heat. Add in the shallots and saute for about 10-12 minutes, or until nicely caramelized. Don’t stir them during this time to allow a nice caramelization to develop. After 10-12 minutes, stir them around gently. Add the garlic on top of the shallots, so it will soften, but won’t burn by making direct contact with the skillet. After 5-7 minutes, give everything a good stir. Add in the olives and parsley and stir to combine, and add this mixture to the cooked couscous, which should be ready by now.
You can now use this same skillet to sear your tofu. Gently place as many pieces as you can into the skillet and saute for 5-7 minutes. Flip the tofu over, and sprinkle with a generous amount of the thyme and black pepper. Continue to saute for 5-7 minutes more. Flip the tofu over again and add a bit more thyme and pepper, then add a few dashes of liquid smoke.Serve immediately with the couscous and a side of some of the unused marinade.
