For many vegetarians, a common question asked of them is, “What about protein though?” Eating a healthy, wholesome, plant based, one can get all the protein needed.
Adding nuts will increase your protein intake in a meal. For example, only 60g of cashew nuts will meet your daily protein recommended amount (*Daily Values are based on a 2,000 calorie diet. Your daily values may be higher or lower depending on your calorie needs.)
Other good sources are legumes, such as beans and lentils.
There shouldn’t even be a question about whether you can get enough protein as a healthy vegetarian. Perhaps one could ask about getting a balanced diet, with enough roughage and nutrients (see a story about getting a balanced vegetarian diet which does not solely consist of cake).
