Curry is ok so long its cooked fresh not frozen bollocks, im sure you have yours proper anyway. Just try and use minimum flower when making it, and have brown rice with it.
Fresh fish isnt that expensive tbh mate, cod and haddock is only £2 from asda. Bit of vegetable oil on top, salt and pepper then under the grill for 15mins job done!
Tinned tuna is only 70p-£1. Chicken breasts are usually £3-£4 for 3-4 big ones from asda aswell. Steak is probably the expensive one here. And eggs are only £1 for 6 most places.
So you want to build lean muscle instead of a general bulk then cut? This may take longer but you wont have to worry about a fat build up as you would get on a typical bulk.

When lifting weights train no longer than one hour, make sure you do a good warm up before, focusing mainly on the muscles that will be worked out on that day. Small rest between sets (70seconds or so).
I know you wanted to do 4 days, but you can do the cardio and abs at home, the running will be done outside and the abs take no longer than 20mins to do.
If youre not sure on what some those exercises are you can see them here

Hope this helps
