I usually prep dinner when DS is napping as he's a cling-on - so meals have to be super easy here too. We are having lots of salads lately 'cos it's so hot but DS wasn't really eating much of the usual salad type stuff so we've had to expand our ideas:

Salad ideas - the usual cue, tom, lettuce, avo, spinach leaves plus asparagus or snow peas (m'wave for 30 seconds), beans, broccoli, cauli (M'wave a little too), capsicum, raw carrot, mung beans etc, spinach leaves, raw mushrooms, tinned corn/kidney beans/mixed beans/beetroot, olives, gherkins, sundried toms, cheese, boiled egg, some kind of deli meat (ham, roast beef, turkey etc). I'm sure there's other stuff but I can't think atm!

Honey soy chicken drumsticks (mix a spoonful of honey with a spoonful of soy plus a little chicken stock plus water and garlic, pour over the chicken and bake for 1 hour), served hot with cous cous and veg or cold with salad (can be cooked in the oven when DS is napping, so no danger there OR use an electric frypan)

Smoked salmon 'caesar' salad - the usual stuff plus cue, tom, avo, asparagus or whatever else happens to be in the fridge! Also good with BBQ or smoked chicken, or just the vegetarian version and it can be made all in advance.

Omelette (winner with DS) with whatever's lying around - cheese, tom, mushies, bacon etc

Savoury pancakes (pancake batter with grated cheese, carrot, zucchini, herbs and bacon for the meat eaters) and salad

I know it's an oven recipe but we also love lamb cutlets and baked mushrooms with a mix of breadcrumbs, parmesan, herbs and a little water (plus pine nuts and/or pesto if you're feeling adventurous). Smoosh on top of the cutlets/mushies and bake at 180 degrees for 10 mins. You can prep it all in advance and if you cut up some thin zucchini and pumpkin it'll bake in the oven at the same time too (or serve with....salad!). Meal done!

Pies and quiches - make the pie filling in the slow cooker and freeze it! Sometimes we just have the pie filling with pasta or rice

Fried rice in the rice cooker - love our $9 rice cooker

Frozen fish with veg or salad is my lazy meal and one of DS' faves!
