Quesadilla are quick and delicious and you can chuck in whatever you want.
I'll sometimes do a big batch of food in the oven in the cooler morning then we'll eat that over the day. So currently, cold sausages, chicken goujons and pork meatballs baked in tomato sauce.
There's cold rice in the fridge already to go with the meatballs, will microwave and add cheese as needed. I'll make a batch of red coleslaw (red cabbage, carrot, vinegar and mayo) later to go with the sausages and goujons, either on their own or in baps.
DH is fond of a cheese, tuna and jalapeno grilled cheese sandwich.
DD5 enjoys eggs so will have a hard boiled, veggie crisps, carrot buttons, sliced apples, baby bel etc for lunch.
D's isn't into meat so will have a heap of rice with chopped veggies through it, with cheese and a yogurt/cucumber herb dip on top.
I know you aren't into salad but we enjoy a prawn cocktail or chicken bacon ceasar salad and you could just put them in a wrap to disguise the heathly! I usually have cold chicken in the fridge just got this.
