if your only feeding for one,
go to the butcher and buy like $100 worth of various meats. You’ll get a discount for bulk buy too.
Then buy some basic Frozen vegies and some pre-made salids. Might cost $20-30.
Wont take long to cook each meal - you’ll have no junk food to eat and it’ll probable do you 2wks, maybe 3 with a top up on frozen vegies n salid.
But if you got cash to throw away - give em a go.
