Preheat the air fryer to 400°F.

In a bowl, toss the okra with 1 tablespoon of vegetable oil and season with salt and pepper.

Transfer the seasoned okra to the air fryer basket and cook, shaking the basket halfway through, until the okra is tender and lightly charred at the edges, about 16 minutes.

Meanwhile, in a small skillet, heat the remaining 1 tablespoon of vegetable oil over medium-high heat.

Add the minced shallot, garlic, and chile, and cook, stirring, until soft, about 2 minutes.

Stir in the tomato paste and cook for 30 seconds, then add the vegetable stock (or water) and peanut butter.

Reduce the heat to maintain a simmer and cook until the sauce is slightly reduced and thickened, for 3 to 4 minutes.

Remove the sauce from the heat, stir in the lime juice, and season with salt and pepper to taste.

Place the peanut sauce on a serving plate, then pile the crispy air-fried okra on top.

Serve hot.
