·Heat
oil in a large nonstick skillet over medium-high heat. Add onion and cook,
stirring often, until soft and beginning to brown, 2 to 3 minutes. Add
mushrooms, bell pepper, oregano and pepper and cook, stirring often, until the
vegetables are wilted and soft, about 7 minutes.
·Reduce
heat to low; sprinkle the vegetables with flour and stir to coat. Stir in broth
and soy sauce; bring to a simmer. Remove from the heat, lay cheese slices on
top of the vegetables, cover and let stand until melted, 1 to 2minutes.
·Divide
the mixture into 4 portions with a spatula, leaving the melted cheese layer on
top. Scoop a portion onto each toasted bun and serve immediately.
·Tip:
The dark gills found on the underside of a Portobello are edible, but if you
like you can scrape them off with a spoon.
