Cook the Fake Meat: In a skillet over medium heat, add a little oil and cook the fake meat crumbles according to package instructions. Once cooked, add half of the umami dressing to the crumbles and mix well. Cook for another 2-3 minutes to let the flavors meld. Set aside.
Prepare the Refried Beans: In a small saucepan, warm the refried beans over medium heat until heated through. Stir in the remaining umami dressing and mix well.
Assemble the Tostadas: Spread a layer of the umami-flavored refried beans on each tostada shell. Top with a layer of the seasoned fake meat crumbles. Add shredded lettuce and sprinkle with shredded cheese. Optionally, add avocado slices and salsa or pico de gallo for extra flavor and texture.
Serve: Serve immediately and enjoy your delicious vegetarian tostadas!
