Tasty healthy meals, on a budget.

As most of us in this day in age, im bloody skint, i really want to be able to make nice, healthy meals that wont cost £15 per time.
A meal in my house has to always have meat in it, we can go 2 days with a meal meat free, this is usually pasta bake, or Mac cheese, but we sometimes put bacon in.
My OH is the fussiest person in the world, he likes something but we eat it that often he goes off it, he doesnt really eat fish, or lamb, cheap cuts of meat (yes i know, he pretends to be a snob) no the reason he wont eat cheap cuts of meat or lamb, is the fat and grisstle content, he literally gags if he has a little smidget of fat or grisstle in his mouth.
So... he likes to have pasta only once a week but not every week, bcos its 'boring' same with fish. i suppose the easiest thing to make him happy, pork or chicken.
we sometimes have gammon steaks with chips and beans but this isnt very healthy is it. we probably have veg once a week, bad i know!!! but now Malakai is almost 1 and will be having 3 meals a day every day and will also be finger feeding, i wont be able to just blend up leftovers from sunday dinner and give him this all week lol

please help
thanks
