Prep the other ingredients while waiting for water to boil: chop red pepper into ½-inch chunks, and rinse black beans and corn.
Add the orzo to the boiling water and cook until just done, according to package instructions (around 9-10 minutes).
While orzo is cooking, make the dressing by whisking together olive oil, balsamic vinegar, garlic salt, and pepper in a large bowl.
When orzo is finished cooking, drain it and rinse with cold water. Then add to large bowl with the dressing and stir until all the dressing is incorporated.
Stir in red pepper, corn, black beans, and parsley.
Season to taste with salt and pepper—or extra garlic salt, if you prefer.
