Yes! you can definitely make this dish without a pressure cooker. Just heat a pot over medium-high heat and saute the onion, garlic, and rice as directed. Then add the remaining ingredients and bring to a boil. Cover the pot and reduce the heat to low, maintaining a gentle simmer. Cook for around 20 minutes until all of the liquid has been absorbed. Then fluff the rice and add the peas. Cover for 3-4 minutes, then serve.
