Courgettes are mostly water, and that water is why fritters go soggy and fall apart. Salt the grated courgette, leave it ten minutes, then squeeze it hard in a tea towel. You will be surprised how much comes out, and the fritters will crisp properly.

Four fritters with the dip have about 30g of protein, from the eggs, feta and Greek yogurt, for around 470 calories. For a vegetarian lunch that is a lot, and it is what makes this filling rather than a side dish.
The courgette is mostly water, which is why it adds bulk for very few calories. Salting and squeezing does not throw away the goodness: what comes out is mainly water, with a little potassium.
Eggs bind the fritters and bring vitamin D, B12 and choline. Wholemeal flour instead of white adds fibre. The dip uses strained Greek yogurt instead of mayonnaise or sour cream, which keeps the protein up and the saturated fat down.
The honest part is salt. Feta is a salty cheese, often around 3g of salt per 100g, so this recipe adds none beyond the courgette salting, most of which is squeezed out. If you are watching your salt intake, rinse the feta briefly or use half feta and half ricotta.
For women around menopause, protein spread across meals, including lunch, helps protect muscle: see menopause weight loss. To make them gluten-free, use gram (chickpea) flour instead. For another vegetarian egg dish, try the spinach, feta and red pepper egg muffins.
