Preheat oven to 375 degrees F.
Coat tortillas on both sides with cooking spray or olive oil. Place on baking sheet and bake, turning once halfway, until lightly browned and crisped, about 10 minutes. Once out of the oven, immediately sprinkle with salt and pepper.
In the meanwhile, heat coconut cream in a saucepan over medium heat. Add garlic and ginger, and sauté until fragrant, approx 1 minute. Add lemongrass and curry paste, and sauté for another minute. Add the rest of the sauce ingredients and simmer, stirring frequently, until well incorporated and thickened, about 5 minutes. For thinner consistency, slowly add water or coconut milk.
Spread peanut sauce on one side of baked tortilla. Top with chicken and vegetables. Drizzle more peanut sauce over the top if desired.
