Green Pea

Lentils
Lentils deliver far more protein and iron per calorie, making them a stronger staple for filling meals, while Green Peas offer a lighter, quicker-cooking option with a vitamin C boost.
Lentils score higher due to superior protein and iron density, making them a more impactful daily staple. Green Peas remain an excellent choice but function more like a vegetable side than a core protein source.
Heavier, slow-burning fuel and higher protein versus lighter, sweeter convenience and faster prep time.
