Prepare the Ramen noodles according to the package directions - except you will NOT use the seasoning packet and you will drain the noodles.*
While the noodles are cooking, prepare your veggies, if they need to be sliced.
Heat a skillet over medium-high heat with one tablespoon of olive oil.
Saute peppers, onions, and mushrooms till tender-crisp, about 2-3 minutes.
Add the drained, cooked Ramen noodles to the sauted vegetables, gently tossing.
Add the desired amount of General Tso Stir Fry sauce, (use a small amount, toss, and check for taste - add more as needed).
Simmer about 2 - 3 minutes over low heat.
Serve immediately, garnishing with sliced green onion.
*Note, if you are using spaghetti noodles, use an amount equal to one serving.
