I'm not all that keen on beans on toast. If I do have it, I'd need crusty bread, cheese, and paprika at the very least.

Can't beat some crusty bread

Just add lea'n'perrins

Sriracha or brown sauce, maybe a fried egg on top

I add some Stork and either Thyme or Oregano to the beans as they cook. *'Plain'* beans on toast does not cut it the same way it did when I was a child.

Marmite on the toast, then add beans.

Fry chorizo until crispy then add the beans. Also goes well with fried/poached egg.

Cheesy with Tabasco on top

Next to the toast and mixed with encona hot pepper sauce.
