Proper falafel is made with soaked dried chickpeas and deep fried. This version uses a tin of chickpeas and the oven, so a little gram flour holds it together and 15 minutes in the fridge stops it falling apart. Quinoa replaces the bulgur in the tabbouleh, which makes the bowl gluten-free and adds protein.

A bowl has about 28g of protein, all from plants. It comes from the chickpeas, gram flour, quinoa, tahini and pumpkin seeds. Quinoa contains all nine essential amino acids, and eating a mix of plant proteins across the day covers the rest.
Over 15g of fibre a bowl is half the 30g a day the UK recommends, and most adults eat only about 20g. That fibre is the main reason this is tagged for blood sugar.
Chickpeas, quinoa and pumpkin seeds all contain iron. The iron in plants is absorbed less well than iron from meat, but vitamin C helps. The lemon, tomatoes and parsley in the tabbouleh provide it. This matters most for women with heavy periods and for anyone who eats no meat.
The honest part is the calories. At about 660 a bowl, this is a filling main meal. Most of the fat comes from the tahini, seeds and olive oil, which are mainly unsaturated, but it adds up. Use 1 tbsp of tahini if you want it lighter.
Gram flour is naturally gluten-free, but check the label if you need it strictly gluten-free. Sesame, in the tahini, is one of the 14 major allergens.
If you train and eat a plant-based diet, see creatine for women; vegetarians and vegans get little creatine from food. For more chickpeas, try the smoky roasted chickpeas or the Moroccan chickpea and lentil stew.
