Grill the pineapple slices and avocado halves. I don't have a BBQ so I used a grill pan, but if you have a BBQ go for that because the flavour will be even better! Grill for a few minutes on each side of the pineapple until grill marks are formed. Do the same with the avocado, only grilling on face side down.
Prepare the veggies by chopping up the 3 pineapple slices, 3 halves of avocados. Add that to a large bowl with the red pepper, red onion, cilantro, lime juice, garlic, japaleno, salt, and pepper.
Prepare the Shirataki noodles according to the package directions. You can choose to serve the noodles hot or cold, both are great, but I choose to serve them cold. Drain and rinse with cold water to cool the noodles. Toss the noodles with the veggies and serve with an extra slice of pineapple and a grilled avocado half for garnish.
If you are using the canned pineapple slices they are a bit smaller, so I would use 4 to 5 slices
