I feel much the same as the others .

This is what I would do...( I know some if not all has already been suggested.)

1.Put up a roll on toilet paper holder. After that he is on his own.
2.He can buy his own laundry soap and a bottle of cleaner for the bathroom.
3.Bowl of fruit ? Yes I would probably say help yourself if you would like to.
4. I would clean out some space in the Fridge, for whatever he drinks or take out food left overs or lunch meats, snack foods.
5. Maybe clean out a bit of cabinet space for bread bagels cereal or such things.
6. I don't think I would cook bigger amounts that you are already doing. for yourself. 1. That might start a trend of doing so and it could become kind of expected, for 2. You are not in the financial position to spend more money on food. Defeats the purpose of needing the extra money by renting a room out.
7. Walk him through your kitchen so he will know where to find things, show him that cupboard space and fridge space you have for him to use. No one really wants to eat out 3 meals a day for months, sometimes you just want a peanut and jelly sandwich for an example.
8. Have you thought or discussed him having people over? Would you be okay with him having guests in the apartment?
9. Sit down and discuss basic common "rules" for the lack of a better word. Agreements of what is okay and is not okay. Both on same page will make this situation work easily on both sides.

I would start out with a good solid boundaries and as time goes by you and him could "blend" a bit more.
