In a bowl, add the chickpeas and mash until most of the chickpeas are mashed but there's still some texture.
Add in the bell pepper, celery, and onion and mix well.
In a bowl, mix the sauce ingredients until well combined.
Then add sauce to the chickpea mixture along with salt and garlic powder and toss well. Taste and adjust salt and heat. If you like more heat, you can add more hot sauce or you can add ¼ teaspoon of cayenne.
To make the slaw, add the slaw ingredients to a bowl and toss well. Taste and adjust by adding more ranch if needed.
Assemble by placing some greens like baby spinach or some peppery greens on one bread slice.
Then add a good helping of the chickpea mash then top it with the slaw and add another bread slice.
