Combine boiling water and sun-dried tomatoes in a bowl, and let stand 5 minutes or until tomatoes are soft. Drain and chop tomatoes.
Heat the olive oil in a large nonstick skillet over medium-high heat. Add chopped onion, red bell pepper, and garlic; sauté 3 minutes or until vegetables are tender. Stir in the sun-dried tomatoes, soy sauce, and the next 8 ingredients (soy sauce through crushed tomatoes). Bring mixture to a boil; reduce heat, and simmer 20 minutes or until slightly thick, stirring the mixture occasionally. Stir in soy crumbles; cook 2 minutes or until thoroughly heated, stirring frequently. Spoon about 2/3 cup crumbles mixture onto bottom half of each roll; top with top halves of rolls.
