Cook noodles according to package instructions, drain and set aside.
Chop veggies and set aside.
Prepare dressing with, salt, pepper garlic powder, agave nectar (or sugar), vinegar, grape seed oil, and spicy mustard and mix until well combined.
Toss drained noodles and veggies with the dressing in a large serving bowl. Chill for at least 1-2 hours before serving. The flavors will meld and the salad will thicken up the longer it chills.
Store leftovers in the fridge for up to a few days.
