Meanwhile, toss pineapple, soy sauce and ginger in a mixing bowl.
Heat oil in a large nonstick skillet over medium-high heat. Add the pineapple, leaving the sauce mixture in the bowl, and cook just until it starts to turn brown. Scoop it out and put it in a large mixing bowl.
Toss the shrimp with the sauce and then add the shrimp and the sauce to the skillet and toss until it is just cooked through, about 3 minutes. Scoop it out and add it to the pineapple.
Add the pineapple juice and the chili powder to the skillet and simmer for 5 minutes. Add the shrimp and pineapple back to the skillet and give it a good toss.
Add the cooked pasta and snow peas and the peanuts and toss again.
Divide among plates, drizzling any extra sauce on top. Sprinkle with scallions if you like and serve with lime wedges on the side.
Notes
Pasta: We love linguine for this recipe, but any long pasta (spaghetti, fettuccine) will work. You can also use soba or rice noodles if you like – just follow the directions on the package.
Shrimp: We recommend large shrimp to get the best seafood flavor. Fresh shrimp are the best if you can get them, otherwise frozen shrimp will work.
Pineapple: We always go for fresh pineapple cubes from an Actual Pineapple, but drained pineapple chunks from a can will also work.
Snow Peas: These flat, slightly sweet pea pods are in your produce aisle. You can swap different vegetables if you like – in broccoli, bell peppers, chopped onions or even crunchy cucumbers…you be you with the veggies!
