Not sure how helpful my meals are if you only eat fish, but maybe you might get some more ideas if nothing else.
Breakfast:
Weekdays - coco pops & semi skimmed milk - gets rid of my chocolate cravings

Weekends - 2 poached eggs on 2 bits of toast, spread with extra-light Flora
or a bacon buttie

i.e a few bits of sinless bacon (is this available in the UK?) fried in fry-lite one-cal spray, on a couple of bits of bread, again with extra light flora when I usually have more time and can be bothered to make a bit more effort
**careful with the poached eggs, they don't seem to suit everyone on Xenical/Alli, I just seem to be OK with them...but the yolk is where the fat hides!
Lunch
Either sarnies, made on wholegrain bread, extra light flora, extra light mayo, chicken or turkey slices and loads of salad
Or half a tin of soup, with a couple of peices of toast
Or 2 pittas, stuffed with chicken chunks, extra light mayo and salad
Dinner
Where do I start...if anything we're eating better than we ever did!
Generally chicken, turkey or lean gammon steaks.
Served either with a couple of spuds and steamed veg, or rice & salad.
We might do a stir fry (again using one-cal spray) we're inventing our own marinades right now for the chicken & turkey, and last night I modified a chicken cordon bleu recipe out of a WW cookbook i have...and it was absolutely scrummy.
For a very rare treat we'll grill a couple of sirloin steaks, as lean as we can make them...served up with a mountain of salad and a handful of home-made potato wedges.
For someone who a self-confessed kitchen-phobe who has always *hated* cooking with a passion,so much so that previously hubby did 99% of the cooking in the evening...I'm finding I'm loving coming up with new, fun ways to eat within the 15g fat rule.
The recipe suggestions on here are a brilliant start point, try a few, and don't be afraid to personalise them if you want to try a new twist on it.
Google is also a great resource for those times when you sit there in the evening with a pack of chicken fillets in the fridge and all inspiration has left you!
Easter is coming up in a few weeks, the same weekend as my 'stick-insect-thin' hubby's birthday..and he's kind of sad at the thought of Easter and birthday being a chocolate free zone in this house...so I'm planning to surprise him with the fat-free chocolate cake that someone put the recipe up for recently...and once he goes back to work he can take the rest in with him, so its not sat here in the house tempting me!
