Some of my quicker 'go-to's are:
Thai curry (using a ready made paste) with loads of veg (broccoli, green beans, sugar snaps, aubergine, cauliflower and a handful of baby corn/carrots but take it easy on those) and a protein. We're vegetarian so I use tofu or boiled eggs but you can throw in anything you fancy.
Egg roll in a bowl; stir fry grated carrot and cabbage with minced tofu/pork/chicken. Add soy/oyster sauce for flavour and top with finely chopped spring onions and a sriracha mayo.
Halloumi, courgette and tomato stew; just cube halloumi and courgettes, dry fry with a wee bit of garlic so they go a little crispy on the edges and then add a can of tomatoes (the cherry tomatoes are really nice in this). You can also add white beans (butter/cannelini if you don't mind a few carbs). Season and I add some chilli flakes for taste.
Taco salad (I make taco 'mince' with finely chopped walnuts and mushrooms but obviously you can just use regular mince) with kidney beans, tomatoes and chipotle. Make a chopped salad (lettuce, cucumber, avo etc.) and top with the warm taco meat then top that with sour cream/greek yoghurt with lime juice and a little cheese.
All of these are really easily adapted for anyone not eating low carb with added rice/noodles/bread/taco shells.
Best of luck with the weight loss!
