Well if it was our house and I needed to do 7 meals I know Olly would eat it would look like this
1 - spag bol (always have bol in freezer)
2 - roast dinner (for a weekend)
3 - jacket potato - prob with ham and a cold veg like avocado or cucumber (spud in micro then crisp in oven)
4 -pasta with tom sauce and meatballs (decent packet meatballs (or make and freeze), dolmio pouch for sauce or make big batch and freeze in portions)
5 - waffles, fish fingers/chick nuggets and peas (freezer)
6 - chicken fried rice (with left over chicken - or use packs of cooked chicken, can use pre cooked or frozen rice)
7 - sticky chicken with rice (thids is a recipe that takes about 40 mins to cook)
They are about the only meals I know Olly will eat really. Oh I will sneak in number 8 - sticky salmon with quinoa (about 20 mins to put on table)

TBH I normally prefer 'proper' cooking but I have included short cuts for you too

When I look at this this is pretty much what most weeks look like for Olly!
