Tomato Pie

274 kcal a serving, against 513 for the traditional version. That is 239 kcal off, or 47%, with 12.9g of protein. Serves 6. 1 hour 10 minutes.
What the traditional version is
The classic tomato pie starts with a blind-baked shortcrust pastry shell. That's filled with a thick layer of seasoned, sliced tomatoes (about 900g), drained well. Next, you mix 200g mayonnaise with 140g grated cheddar and a handful of chopped fresh basil, spread the topping over the tomatoes, and bake until golden and bubbling. Let it cool before slicing or risk tomato lava everywhere. The butter in the pastry and the full-fat mayonnaise supply most of the calories, and you aren't getting much protein per bite.
What changed, and what each change costs
No pastry case, bake as a gratin
Pastry is glorious, but it brings 1,000 calories and almost no protein for its trouble. Skipping the base ditches a big chunk of fat and lets you eat a portion without feeling heavy.
What it costs you. The first thing you'll miss is structure: you'll scoop, not slice. You lose that contrast of crisp pastry against soft tomato. The flavour's there, but the neat wedge is gone. There's no pretending otherwise.
Mayonnaise halved and cut with fat-free Greek yoghurt
Full-fat mayo is the second reason this pie is a wallop. Swapping out half for yoghurt lightens it up and adds protein, so you get a creamy topping that hits the right spots - even if it's a bit tangier.
What it costs you. The topping isn't as thick or as unctuous as the old-school version. It's more creamy-dressed salad than mayo bomb, though the cheese keeps it from being all virtue and no flavour.
More cheese, and swap in extra-strong cheddar
The mayo's been cut, so more cheese brings back some richness and, crucially, boosts protein per forkful. Go for extra-mature cheddar or similar so you need less for the same punch.
What it costs you. It costs you nothing on taste - if anything, this is the best upgrade. It isn't 'cheese pie', don't worry, but the flavour is stronger and it almost convinces you it's still decadent.
Layer a handful of whey protein in the topping
A bit of unflavoured whey protein powder stirred into the cheesy layer lifts the protein much higher without changing the texture once baked. The cheese and mayo cover any hint of 'gym bag'.
What it costs you. If you go over 15g, you risk a grainy topping. At this amount, you'll never know it's there. If this offends your sensibilities, leave it out and settle for less protein - your call.

The method is in the book
The flavour is all there - sweet tomato, sharp cheddar, that slight tang from the yoghurt and mayo blend. No one's pretending this is proper pie. You lose the slice but keep the taste. If you desperately miss the pastry, eat it with a bit of good bread on the side and move on. The protein is much higher and you can justify seconds without pushing your luck. If you find yourself thinking it's actually better than the original, check your head - I like it, but I'm not delusional.
