A few ideas for meals :
Breakfast : scrambled eggs, add what you like for variety I’ve smoked salmon, mushrooms, onions, a small amount of Parmesan or feta, tomatoes
Cottage cheese with diced apples or pears with a slice of ham chopped up
Yoghurt with berries ( I add half a tsp of date syrup to sweeten)
A couple of rashers of lean back bacon , grilled ( fat removed) with mushrooms, tomatoes, or beans or egg
Frittata, with veggies of choice and a sprinkle of Parmesan
Mushrooms stuffed with chopped leeks , spinach and a small amount of Wensleydale
