It's no secret that eating a range of vegetables is recommended for a balanced diet. Whether it's as a side or as an integral part of your meal — think salads — veggies play an important role. But "protein-rich" isn't an adjective that usually comes to mind when discussing vegetables. Even for some folks who are plant based, roasted and raw veggies play bit parts where protein-packed mains like meat, fish, eggs, and poultry maintain a starring role.
