Step 6:

Some may note a slight visual resemblance to the British classic Bubble and Squeak. Indeed, this preparation, if properly compacted, will itself bubble and squeak to a degree. Much like the British dish, you want to get some bits and pieces of this vegetable/bacon mixture to brown very dark, perhaps even begin to burn. When the vegetables have lost a significant amount of their volume and some have attained a crispy texture and dark color, add enough freshly-brewed coffee to cover the lot.

Stir briefly, then cover and simmer at least one hour. Add more coffee as necessary to keep everything covered.

The vegetables should break down somewhat, though not completely.
 

 Step 7:

When they have reached appropriate doneness, open the cans of beans.
