Preheat oven to 350F. Stir together all the spices and rub on the pork tenderloin. Toss zucchini pieces with 1 tsp olive oil and 1/2 tsp each salt and pepper. Place pork and zucchini on a sheet pan lined in foil.
Bake the pork in the oven for 20 minutes or until the internal temperature reads 140 F.
Remove the pork from the oven and slice once cool enough to handle. Serve with zucchini.
Pressure Cooker/Instant Pot
Cut pork in half. *If pork is frozen, put cooker on saute mode. When ready, add 2 tsp oil and brown on each side. Remove from the cooker and add seasonings. **If pork is not frozen, cover with seasonings and then put cooker on saute mode. When ready, add 2 tsp oil and brown on each side.
Remove pork. Without scraping bottom of the pan, add zucchini and saute 3-4 minutes or until cooked to desired texture preference. Remove and cover to keep warm.
Return pork to cooker. If frozen, select the 'meat' function for 15 minutes. If fresh, select 'meat' function for 6 minutes. *Can skip the saute step and cook high pressure for 8 minutes instead.
When cook time is finished, leave cooker to naturally release steam about 8 minutes. Move the steaming valve to open, keep face away from valve. When the lid turns easily, open slowly. Remove pork. Slice and serve with zucchini.
