Peanut noodles

I got this recipe from one of my cafemom groups

1/2 cup low or no sodium vegetable broth
1/4 cup chunky peanut butter (I use smooth)
1/4 cup low-sodium soy sauce
3 tablespoons brown sugar
2 tablespoons rice vinegar
2 teaspoons grated peeled fresh ginger
2 teaspoons chile paste with garlic (add to taste, it is pretty spicey)
4 garlic cloves, minced
8 ounces uncooked whole wheat angel hair
1 pound firm tofu, drained and cubed (optional)
1 cup (2-inch) sliced green onions
1 cup shredded carrot
Combine first 8 ingredients in a small saucepan. Cook over medium heat 5 minutes or until smooth, stirring frequently (this can also be done in the microwave; use a tempered glass bowl, like pyrex, cook for 20 seconds, stir, repeat until smooth). Remove from heat. Cook pasta in boiling water 8 minutes, omitting salt and fat. Add tofu, onions, and carrot; drain. Place pasta mixture in a large bowl. Add peanut butter mixture; toss gently
