Oh dear - we could have written the same post! I too am a bit stuck. Here are some of our favourites:
Fritata (fried cube potatoes, spring onion, leftover veg and any meat/quorn bits we've got to hand... then 1/2 a HEXA of feta) we normally have salad with this
Pulled Mexican chicken (essentially slow cooker chilli but with chicken instead of mince, you simply poach in the sauce then remove when cooked and shred it before returning to cooker)
Stir fry (leftover veg and simple sauce of blitzed coriander, soy, bit of honey - jarred peppers really good to blitz for sauce as well)
Katsu curry (sw recipe isn't bad at all - sometimes I cheat and use quorn hot and spicy burgers for a couple of syns instead of faffing with chicken)
Low syn or free quorn sausages with mash, veg and gravy
SW wedges with spice rubbed chicken (or fish!) and broccoli
Marinated salmon (use a similar thing to stir fry sauce) with green beans and buttery potatoes (a tbsp of butter will do four portions really, add some chives for extra love!)
Ham, poached eggs and homemade chips (for speed I'll normally scoff something alongside while DP has something sw unfriendly)
Fajitas (syn the wrap or use mini tortilla boat)
SW soup - quite like doing a minestrone as it feels more like a meal
Pasta and meatballs (either quorn balls or sw ones from iceland) with a sprinkle of cheese
Jacket sweet potato with light cream cheese and salad
Hope that helps! I find that sitting down and doing a plan where I mark down where I'll be having my A and B each day really helps. We used to avoid using syns for dinner and the same for HEXA and B as we were too reluctant to miss out in the day. The solution was to compromise and use some syns for extra cheese/nuts/breadcrumbs for dinner as it makes things so much more varied and flexible. From a healthy eating perspective it's also done us the world of good to use syn allowance for nuts or something with nutritional value rather than chocolate (ahem! Not that I've ever done that!!) Xx
