Heat sesame oil in a large skillet over medium heat until it smells like you know what you’re doing.
Toss in onion, bell pepper, and carrot. Sauté for 5 minutes until just tender—like your last relationship.
Add shredded jackfruit and let it brown slightly, about 7 minutes, stirring occasionally like the multitasker you are.
Stir in pineapple, soy sauce, vinegar, maple syrup, and tomato paste. Mix it all like you’re stirring tea on Instagram.
Let everything simmer for 5 minutes, then add cornstarch slurry. Stir constantly until sauce thickens up like good mascara.
Season with salt and pepper to taste. Sprinkle with sesame seeds and green onions if you’re feeling fancy.
Serve hot over rice, noodles, or your favorite carb blanket.
