Funny punny title, yes. What it means is that today’s food is pesto made with peas instead of basil. And it’s real easy too.
2 parts green peas (fresh or defrosted)
1 part oil
1 part whatever kind of nuts or seeds you like
1 part grated parmesan cheese or similar.
Mix all the stuff and blend it to desired texture. Adjust thickness with oil and cheese or more peas. I use a hand blender and get it ready in almost no time at all. The pesto in the picture has more cheese and peas instead of nuts since the pine nuts were way too expensive and my wife dislike sunflower seeds and is allergic to most proper nuts. It works beautifully with for example pasta anyway.
