Heat olive oil in a skillet over medium heat. Stir in onion and garlic; cook about 5 minutes. Then add thawed peas to the onion/garlic sauté mixture for just a couple minutes to heat through. Stir in stock Season with salt and pepper. Cover, and cook until the peas are tender.

This way, you'll avoid the wrinkly and mushy look of overcooked frozen peas, and the peas will stay a vibrant green color. The flavor of this dish is great and is a nice change from the same old blah peas.
