Instructions
Roast the Cauliflower:
– Preheat the oven to 425°F.
– Arrange the cauliflower florets on a baking sheet; drizzle with olive oil and sprinkle with salt.
– Roast for 25-30 minutes until browned and tender.
– Add taco seasoning directly to the pan; toss with the cauliflower using tongs until well coated. (You might not need the entire seasoning packet.)
– Return to the oven for 5-10 minutes to enhance flavor.
Prepare the Tostadas:
– Heat 1/4 cup of oil in a large skillet over medium heat.
– Once the oil is hot (a drop of water should sizzle upon contact), add the tortillas, a few at a time.
– Fry each side for a few minutes until golden brown and crispy.
– Place fried tortillas on a paper towel-lined plate to drain excess oil. Repeat with remaining tortillas.
Assemble the Tostadas:
– Spread warmed refried black beans over each crispy tortilla.
– Top with roasted cauliflower florets.
– Garnish with cilantro and pickled red onions.
– Drizzle warmed queso over the top.
– Season with additional salt and a squeeze of lime juice, if desired.
Notes

– Place slices in a jar; fill about 1/3 with white vinegar and the rest with water.
– Add a pinch of salt and sugar; shake to combine.
– Refrigerate for at least 1 hour before use.
– Pickled onions can be stored in the fridge for 3-5 days.

Cook techniques
Roasting Cauliflower
Roasting cauliflower enhances its natural flavors and gives it a crispy texture. A high oven temperature, like 425°F, allows for caramelization and deep browning. Drizzling with olive oil and seasoning with salt beforehand ensures even cooking and flavor infusion.
Frying Tortillas
Frying corn tortillas in hot oil transforms them into crispy tostadas. The key is to heat the oil to the right temperature, where a drop of water sizzles upon contact. Frying in batches prevents overcrowding, allowing each tortilla to achieve a golden brown color.
Assembling Tostadas
Layering the tostadas involves spreading a base, such as refried black beans, followed by toppings like roasted cauliflower, cilantro, and pickled red onions. Drizzling warm queso on top adds richness and flavor. A final touch of salt and lime juice can enhance the overall taste.
