I am going to share my menu for the next week or so in the hopes that I will actually remember to make everything I planned. My BF and DD will still be eating their regular foods, so I am going to include what I plan to serve them as well. Ideally, most meals will be something we can all enjoy, but that isn't always possible.
Breakfasts:

avocado halves stuffed with smoked salmon & cream cheese

scrambled eggs, bacon, tomato slices, sauteed mushrooms

breakfast sausage, fried egg, tomato slices, cauliflower patties

soft boiled eggs w/asparagus

low carb leftovers from dinner for breakfast

Eggs Benedict w/low carb multi grain English Muffin half (or just without the muffin)
For the rest of the family, they also have homemade waffles, cereal, oatmeal, English muffins to choose from. I will probably bake some banana muffins for them as well.
Lunches:

Squash Soup w/side salad and some slices of deli meats/cheese rolled up

Nicoise Salad (with green beans, lettuce, cucumbers, cherry tomatoes, cheese, hard boiled eggs, vinaigrette dressing, tuna)

Veggie or Cheese Omelette w/side salad

Salmon Fish Cakes w/sauteed cabbage (or just a homemade coleslaw) or Salmon Salad Sandwiches (using lettuce for mine instead of bread)

Chef's Salad
For the rest of the family, they also can have PBJ or deli meat sandwiches, ravioli, other types of soup/ramen.
Dinners:

Marinated Steaks w/Asparagus and a small side salad

Roast Chicken with Gravy, Broccoli, Boiled or Mashed potatoes (for them), rolls (for them), corn

Chicken Breasts with Basil Cream Sauce, with mashed cauliflower and a small side salad

Indian Style Chicken & Vegetable Curry w/cucumber raita, Naan bread (for them) w/basmati rice (for them)

Fish w/tomato & cucumber salad (Chicken Sandwich for my BF)

Personal Cottage Pies (using mashed cauliflower instead of mashed potatoes on my portion)
Sometimes the meals will get repeated (especially for breakfast and lunch) but that is the basic plan I follow to get me back on track. I avoid diet soda, drink water & unsweetened iced tea mainly, as well as hot coffee (with cream, no sugar) and green or herbal teas (nothing added).
I am never totally strict about every carb, because it just isn't realistic. I just try to make my meals as reduced in carbs as I can, without loading on too much excess fat (although I stick to whole, real versions of things like butter and other dairy). Meats are always lean/skinless when possible and the meat fat gets drained.
I will try to eat this menu over the next
two weeks, then add in some other dishes so we don't get bored. I vary the way each dish is made when it gets repeated, such as using a different seasonings/herbs/vegetables, but keeping to the basic menu ideas.
