How to Make It
Preheat oven to 400°F. Combine vinegar, 1 cup water, sugar, and 1/2 teaspoon salt in a saucepan. Bring to a simmer; cook until sugar and salt dissolve. Stir in carrot, cauliflower, and radishes. Remove from heat.
Cut 4 circles from each tortilla with a 2-inch round cutter. Place on a baking sheet. Bake at 400°F for 9 minutes.
Place jackfruit in a bowl, and shred. Stir in lime rind, juice, chile powder, cumin, garlic, pepper, and remaining 1/4 teaspoon salt. Place in a nonstick skillet; cook over medium-high, stirring often, 3 to 5 minutes.
Top each baked tortilla circle with 1 teaspoon jackfruit mixture and a few pickled vegetables. Sprinkle with cilantro.
