Here are a few options, though, depending on the context:
Informal:
* A pot of baked beans
* A bowl of baked beans
* A pile of baked beans
* A heap of baked beans
More playful:
* A symphony of baked beans (alluding to the sounds of bubbling beans)
* A chorus of baked beans (similar to the above)
Ultimately, the best choice will depend on your specific writing style and the desired effect.
