Sonoran Hot Dogs - the veggie version

How to make a Sonoran hotdog for vegetarians?  They sounded delicious, based on the description.   Bacon-wrapped dogs encased in a bun, smothered in beans, salsas, cheese.....

Fine Cooking and Sunset had some nice recipes. 

We have made a variation on these twice recently with no special ingredients on hand:

• Store bought wheat buns (I'll make the effort to hunt down bolillos at some point)
• veggie bacon - we didn't have this, so next time
• smart dogs
• grilled onions
• pico de gallo (diced tomato, onion, cilantro, jalapeno, lime, salt)
• mustard, mayo
• black or pinto beans
• shredded cheese
• avocado
• shredded lettuce

WARNING:  these are addictive!
