A Caesar salad usually gets its creaminess from mayonnaise or a lot of oil. This dressing uses Greek yogurt, with Parmesan, anchovy and garlic for the punchy flavour, so it still tastes like a proper Caesar. Make the dressing first.

A serving has about 52g of protein for around 440 calories, which makes it one of the most protein-dense meals on this site. Almost half of its energy comes from protein, mostly from the chicken.
Where the calories are saved. A classic Caesar dressing is an emulsion of oil and egg yolk, and many shop-bought versions are made with mayonnaise. Swapping most of that for Greek yogurt keeps the creamy texture with far less fat, and the yogurt adds protein of its own.
The flavour comes from three salty ingredients: Parmesan, anchovies and mustard. That is why there is no added salt. Anchovies are a traditional part of the dressing; leave them out if you prefer, and add a few capers instead.
Low in carbohydrate, high in protein. That combination is why this is tagged for blood sugar. If you train hard or want a bigger lunch, add a tin of cannellini beans or a portion of cooked new potatoes.
Traditional Parmesan is made with animal rennet. The croutons contain gluten; use gluten-free bread if you need to. For another high-protein salad, try the steak, rocket and Parmesan salad. For why protein matters more as you get older, see strength training in midlife.
