Directions
In a large bowl, combine the tomato, green onion, chopped cilantro, garlic, and as much of the minced chile as you like. Halve and pit the avocados, then scoop the flesh from the skin and add to the bowl. Squeeze the juice of 1∕2 lime over the avocado. Using a fork, mash the avocado coarsely, incorporating the other ingredients in the bowl as you work. Season with salt and add more juice from the other 1∕2 lime as needed to achieve a guacamole with good flavor.
Top the tostada shells with the guacamole, dividing it evenly and spreading it to the edges. Top each tostada with the romaine and then with the crab, dividing them evenly. Drizzle each tostada with 2 teaspoons crema. Garnish with cilantro leaves and serve immediately with the lime wedges and with the hot sauce, if desired.
