Another option is using those plastic shoe holders with the pockets in them. I think you can actually buy a herb specific one from bunnings for about $5. You can just hang it over a fence or railing and fill each pocket with soil and plant your herbs.
As for spag bol, i only ever use lentils or tvp- no meat here.
For the sauce i use garlic, onion, tinned tomatoes, tomato paste, oregano, rosemary, mixed herbs and sometimes others.
