Family meal ideas

So I’m in need of some new ideas with school holidays around the corner. I only work school terms so am home during school holidays with my kids. I’ve always done a fruit platter for morning tea with an assortment of fruits - apples, pears, watermelon, grapes, mandarin, banana and oranges, another platter for afternoon tea with carrot, cucumber, celery, baby tomatoes, cheese and crackers (usually rice, sometimes jatz). For breakfast they have toast or cereal through the week then pancakes or scrambled eggs on weekends.
Because I’m home during school holidays I do things like spaghetti bolognaise, creamy chicken pasta, Shepard’s pie, sausage hotpot, tacos, enchiladas or butter chicken for lunch then roast meat and veggies for dinner. I always do buttered bread with hot meals. And the kids have yogurt or custard after dinner if they want it.
But I feel like I’m cooking the same thing over and over. During school terms the kids and I all take sandwiches for lunch so I try not to do sandwiches during school holidays however usually in the six week Christmas holidays I’ll do a sandwich platter once a week.
I’m really needing some simple meal ideas to keep these kids interested. Ideally something that can be whipped up easily enough as usually my eldest and I prepare everything in the mornings before I’m waking the rest of the kids up.
My children are pretty good eaters with no allergies other than seafood. Any ideas for any meals will be highly appreciated!
