Reconstitute the soy curls by placing them in a bowl and pouring the hot water over them. Let them sit for about 15 minutes. Drain the soy curls and squeeze out any excess liquid.
Place 1 teaspoon of olive oil and the bouillon cube in large pan over medium high heat. Stir until the cube begins to dissolve.
Add the soy curls and ¼ cup of the marsala wine. Cook until the soy curls begin to brown, stirring frequently, about 5 to 10 minutes. Remove them from the pan and set aside.
Add the remaining olive oil to the pan and cook the onion, until it starts to brown slightly, about 5 minutes.
Add the garlic, mushrooms, salt and thyme and continue cooking until the mushrooms have started to brown, about 5 more minutes.
Add the marsala wine and vegetable stock to the pan along with the cooked soy curls. Bring to a boil and the reduce heat to medium low. Simmer for 5 to 10 minutes or until the liquid has reduced by half.
To serve, place about a cup of mashed potatoes, cooked pasta, or cooked rice in the bottom of a shallow bowl. Place a handful of the arugula on top of each, and then top with the soy curl mixture. Garnish with chopped parsley.
