Cook Time
  • 1tbsp vegetable oil(approx.)
  • 8 Corn tortillas6-inch
  • salt
  • 20ounces pineapple chunks,with juice 1 can
  • 1/2tsp hot pepper flakes
  • 3/4cup Water
  • 1-1/2lbs skinless tilapia filletscut into large pieces
  • 1cup deli-packed coleslaw
  • 1 avocadocut into chunks (optional)
  1. Set your Instant Pot to Sauté on Normal. When the display says Hot, add 1 tsp oil, turning pot to coat bottom, and heat until shimmering. Add 1 tortilla and cook, turning once, for 2 minutes or until lightly browned. Transfer to a plate lined with paper towel. Season with salt. Transfer drained tortilla to a foil sheet. Repeat with the remaining tortillas, adding more oil as necessary between tortillas and stacking drained tortillas on the foil. Wrap tortillas in foil to keep warm. Press Cancel.
  2. Set aside 2 tbsp pineapple juice. Add pineapple and the remaining juice to the pot. Stir in hot pepper flakes and water. Add tilapia on top, overlapping as necessary; do not stir.
  3. Close and lock the lid and turn the steam release handle to Sealing. Set your Instant Pot to pressure cook on Low for 3 minutes.
  4. When the cooking time is done, press Cancel and turn the steam release handle to Venting. When the float valve drops down, remove the lid. The fish should be opaque and should flake easily when tested with a fork. (If more cooking time is needed, continue pressure cooking on Low for 1 minute.)
  5. Meanwhile, stir reserved pineapple juice into coleslaw.
  6. Layer 2 tortillas, mostly overlapping, on each serving plate. Using a slotted spoon, spoon fish and pineapple onto tortillas. Top with coleslaw. Serve garnished with avocado, if desired.
Recipe Notes

You can substitute store-bought tostada shells for the tortillas and omit the oil and salt. Skip step 1. Before assembling the tostadas, heat the shells in the microwave on High for 10 to 20 seconds or until warmed.

If your Instant Pot doesn’t have a Low pressure setting, cook on High for 1 minute.
