Heat olive oil in a deep stir fry pan on medium-high
When the oil is heated, add frozen shrimp and saute one side for 3-5 minutes or until pink
Flip shrimp over to uncooked side and add frozen veggies on top. Let the veggies thaw while the shrimp continues to cook (about 3 minutes). Once the shrimp is cooked through you can stir it up!
When the veggies are no longer frozen and almost cooked, add the udon noodles on top to heat and steam. Do not stir yet. Let the noodles sit for 2 minutes before combining.
Add your peanut lime vinaigrette or sauce on top. Wait 30-60 seconds and combine.
Plate your peanut lime stir fried udon noodles.
Top with roasted peanuts and chopped romaine lettuce. Serve hot!
