1.Preheat an oven to 400 degrees F.
2. Combine the pineapple ginger sauce ingredients in a mason jar and shake well to combine.
3. Marinate the pork for with about 3/4 of the sauce for ~60 minutes.
4. Slice half a pineapple and add to a parchment lined baking sheet. Give them a light oil spray and light drizzle of maple syrup. Cook in the oven for ~10-15 minutes (flipping half way). You want these to get some nice browning, but not to dry out.
5. Bake the pork tenderloin in the oven for ~ 10 minutes. Re coat the pork tenderloin with the other 1/4 of the sauce. Continue to bake for ~5-10 more minutes until the internal temp of the pork reaches 155 degrees F.
6. Let the pork rest for a few minutes. Slice and drizzle over with the sauce at the bottom of the sheet pan.
7. Eat the pork slices with the pineapple for a delicious combo of flavours!
