Thank you Jammyrella, that sounds like a good alternative.
Unfortunately, my eldest (who's the macaroni addict in our house) is autistic and has to have every meal done exactly the same way every time - especially his beloved macaroni cheese - he's also gluten free, which makes life that bit more interesting when cooking for him. 
Maybe I could make him a normal one and do myself a mini-version of your recipe.
I've come in way under my MFP calories again and am starting to worry that I'm not eating enough, although I'm not hungry, feel like I'm eating healthily and am not doing much in the way of exercise most days. I do know I need to increase the number of intakes I'm having, as I'm not remembering to fit any snacks in, so maybe that will help bridge the gap.
A typical day (eg today) for me so far has been:
Breakfast: Porridge made with water and a Pukka Detox Tea
Mid morning: Decaff coffee with skimmed milk
Lunch: Wholemeal pitta with a low fat hoummous, half an avocado, cherry tomatoes, celery, cucumber, spring onion and lettuce (we're talking a BIG pile of salad here - have to eat it with a fork as it won't stay inside th pitta) and a Pukka Cleanse Tea
Tea: Quorn peppered steak with steamed carrots, cauliflower, broccoli and peas (or mange tout, sweetcorn, spinach, fine beans)
Evening: Decaff coffee with skimmed milk
Pukka Nightime tea before bed
I think I possibly need to add some fruit into the porridge (blueberries or strawberries) and find a suitable snack option for mid-morning and afternoon. Have just ordered some fat-free natural yoghurt, so could perhaps sling a bit of fruit in that for one and maybe have nuts for the other? I want to keep it as fresh and unprocessed as I can and tend to avoid 'diet food' like weightwatchers cakes etc, as they just make me crave things I shouldn't be eating.
What do you ladies think - how can I improve on the above?
Also, Lambskin MFP keeps telling me I've gone over my fat intake by between 4 and 7 grammes, despite being well under my calories, yet I haven't eaten any saturated fat at all since last Wednesday. Do you think this is worth bothering about, considering I'm only eating 'good' fats?
