Some good tips? Get a slow cooker, too easy to cook roasts in there & then slice it up & leave in the fridge - so you have a big stack of cooked meat ready to go!
Next, on a home day I slice up a lot of onions, capsicum with herbs & caramalise with olive oil & balsamic, sometimes I add mushroom, whatever veg you like - this is the base. This is the most important thing, it provides a really nice sauce that stops food from being dry and/or boring.
This vegetable base sits in the fridge & you can add in to eggs in the morning, with spinach, for an omelette. You can add it to a lunch salad, wrap or toasted sandwich. You can top it with a fried egg for lunch.
At night grab some of the meat, & add to the veg & dinner is almost ready.
If there's a particular veg you want to add, then you are just cooking one thing at night, when your tired & hungry, like broccoli, asparagus or fennel & then adding to what is already ready. I stir through spinach most nights.
Melt some blue cheese on top if you like (makes everything fancy!!!) Any non paleos or kids add some rice or pasta. Stir through cream or sour light cream if you like.
Dinner is done - its paleo, but you can adapt it for non paleo eaters.
good luck!
