My DS is 3 and trying to think up dinners gets exhausting! DH works shifts so we often eat at different times which complicates things. Prepping meals alone is a nightmare, he always needs help when I’m holding raw chicken or at a fiddly bit!
The NHS food 4 life site has some simple recipes for healthy snacks and dinners. There’s an egg one you bake in muffin trays that DS used to like for his lunch. You can add and substitute veg to your DC preference.
Could you try some old faithfuls but substitute red meat? Like spaghetti bolognese, tacos or chilli with turkey mince. I add thinly sliced celery, red pepper cut into really small cubes, grated carrot etc to lots of meals to up the veg. Asda and Morrison’s do a lovely frozen Mediterranean vegetable bag which works great to pad out pasta dishes.
Tacos are great because you can buy ready made guacamole and sour cream and just brown the turkey mince, season and warm the shells. I make a kid friendly salsa from cherry tomatoes chopped, spring onion, a bit of lime juice and some parsley.
I make a vegetarian bean stew from the Ella’s kitchen cookbook which is super easy just in one big pot and it freezes well so you can keep small portions back for lunches.
Slow cooker meals are great too as you can prepare them when you get 5 mins (ha!) or in stages through the morning when they’re distracted and just turn it on. A blog called Taming Twins has some great slow cooker recipes. I’ve done the chicken casserole and honey garlic chicken and both were lovely. She also has batch cooking recipes which I’m going to try next.
