This was Drew's first vegetable (He was 5 1/2 months old). So easy to make, and he actually liked right away. And for those that are unsure (like I was), sweet peas and green peas are the same thing.
Recipe: 2 cups of frozen peas (you can use fresh if you can find them). Steam until bright green and tender (about 5-7 minutes for fresh or hard frozen and 3 minutes for thawed frozen). Puree peas in a food processor or blender until smooth. Add water, breast-milk or formula to thin puree to your desired consistency. I made mine a little on the thicker side. That way, when I thaw it out I can add warm water or breast milk. This warms it up a bit and thins it out at the same time.
I scooped up the puree into an ice tray, put in freezer until frozen, than took them out of the tray and put it in a zip lock bag. This makes it easier to thaw out one serving at a time. These keep in the freezer for up to three months.
