Hi, this is a really good idea, the trouble is what he will like is different to what i like so it a difficult one, maybe divide the problem into meals.
breakfast, i eat full fat greek yogurt (fage) with mixed berries and sprinkled with milled flaxseed, if you think he might like this breakfast is sorted otherwise eggs and bacon is good or an omelette
lunch, salads with cold meat and or cheese, there are alot of different ways to make a salad interesting
dinner, i would make a list of seven meals you both like,
monday: home made curry on a bed of lettuce and raw sliced onion (put lemon juice on the lettuce before you add the chicken (yummy))
tuesday: i hate tuesdays so tuesday is steak night lol fried on a hot grill and serve with fried mushrooms and asparagus (again yummy)
wednesday: spaghetti bolognaise minus the spaghetti, i have the mince with a homemade dolmio type sauce with leeks instead of spaghetti
thursday: chicken stirfry, you can add all kind of stuff its very versatile
friday: home made cheese burgers (you could try stuffing with cheese and crispy bacon) wrapped in lettuce
saturday: lamb chops with a teaspoon of apple sauce then grill melted cheese over the top, serve with giant mushrooms stuffed
sunday: roast dinner replacing the spuds with cauliflower mash and extra veg
afters: double cream with sugar free jelly or make some low carb cakes/puddings
snacks: nuts nuts nutssss lol or berries if you havent had them for brekkie or a few squares of 85% dark chocolate, you can combine the chocolate with the nuts in your mouth and its like eating ferrero rochet....*cough* so ive heard
my list is pretty useless as its the kinda list i would like, you have to come up with something you guys like, the trick is in the planning in advance, the problem with avoiding convienience foods is its inconvienient
, i used to spend hours looking for different ways to cook my favourite meals and its hard to think of a single thing that i dont prefer to the old high carb meals, i think if your enjoying what your eating who cares what is (or isnt) in it, so mke scrummy meals and its easy to stick to, its a pain in the **** but so worth it
i hope something here makes sense
best of luck
edit: these are just examples they can all be modified with all kind of stuff
