Add olive oil, diced zucchini, black pepper and garlic powder to a medium sized pan over medium-high heat. Saute for 1 to 2 minutes then set aside.
Bring a pot of water to a boil. Add the orzo and cook according to the package instructions (mine was 8 minutes to al dente). Drain the water then place the pot of orzo back on the stove over low heat.
Add milk, cooked zucchini, and grated parmesan to the pot of orzo and stir everything until combined for about a minute. The cheese should be all melted and orzo looking really creamy.
Serve right away!
