Last week I did BIWIs bootcamp which is pretty hardcore low carb, so obv you could be a lot less strict! But here is what we had, hope there's some ideas you like:
Breakfasts:
-Eggs scrambled in lots of butter with either bacon, smoked salmon, cold leftover sausages, cold leftover gammon or garlic butter mushrooms.
-Eggs scrambled over spring onions and chilli with grated cheese mixed in (a winner!)
-Herby/cheesey scrambled eggs (thyme & cheddar was good, am going to try basil, chopped tomato and parmesan tomorrow)
-Obv you could do fried/poached/omelette etc, we just like scrambled!
-Greek yogurt
-Want to try smoked bacon + avocado + sliced tomato and topped with grated cheddar, it sounds nice!
Lunches:
-I made mini quiches in muffin moulds with no pastry for a couple of days. Very easy to make - I filled them with fried leeks, broccoli, mushroom, chopped gammon and grated cheese, then the egg & cream custard and bake for about 30 mins. Had with salads.
-Veg soup (think about carby-ness of veg and try to avoid onions, carrots, peas, squash if being strict. Leeks, celery, broccoli, cauliflower, celeriac all much lower in carbs and good in soup) with cheese, cold meat, salad
-Bolognaise sauce on buttered shredded cabbage
-Smoked trout or mackerel fillets (the hot smoked that you can just open packet and eat) with salad of spinach, radish, cucumber, avocado, grated broccoli stalk, spring onions
-Chicken breast fried in spices of choice, mixed with lettuce, cucumber, feta and olives
-Leftover roast pork fried up with sliced fennel, squeeze of lemon at the end
-Leftover roast pork fried with beansprouts, garlic, ginger, soy, five spice, sesame oil, then mixed with sliced spring onions and peeled cucumber strips and served in lettuce wraps
Dinners:
-Roast pork, crackling, mashed swede, broccoli & savoy
-Crispy duck legs with Egg fried cauliflower rice and stirfried broccoli & savoy
-Chicken breast stuffed with butter and garlic, wrapped in bacon, with mashed swede, green veg
-Chicken breast diced and fried with broccoli, leeks, gammon, mushrooms, garlic, in a cream sauce over buttered cabbage
-Cauliflower and broccoli cheese with sausages (if being strict then you can't make the cheese sauce with flour and milk - melt cream, cream cheese and grated cheddar together to make the sauce)
-Smoked paprika & cayenne seasoned chicken legs casseroled with leeks and a tinned tom and stock sauce, served with cauliflower rice and broccoli
-Beef casseroled with swede and celery (and a small bit of onion & carrot), with smashed celeriac and broccoli
-Home made burgers (pig out night!) topped with cornichons, mayo, smokey bacon, melted cheddar, with a big salad and celeriac chips
I think celeriac chips and mashed swede are two big winners for us, you don't really have to think "argh no carbs" as they feel just like the carbs.
Celeriac chips
I also want to try these swede chips as they look really good too.
Cauliflower rice is also very quick and easy and a really useful substitute.
There's a whole Low carb recipe section on MN here and a number of the meals we had were from there.
Hope that helps!
