Add the oil to a large skillet set over medium heat. Add the chopped onion and saute until the onions are soft and translucent, about 4-5 minutes. Add the garlic and cook another 30 seconds more until fragrant.
Add peas, water, and chicken bouillon granules, then cover and cook for 2-3 minutes until the peas are tender and heated through.
Season with salt and pepper. Sprinkle with freshly grated Parmesan cheese, if desired.
