The seasonings are just sea or Kosher salt, fresh ground pepper, some butter for the Acorn squash, and butter flavored non-stick cooking spray. And, that's all there is to it!!
ROAST PORK TENDERLOIN w/FRESH ROAST ASPARAGUS and ACORN SQUASH
Preheat your oven to 375. Line a rimmed baking sheet (or 2, if you're doing more than 1 tenderloin and squash) with heavy duty foil. Put a rack on the foil (large enough for the pork and the asparagus ~ but leave space for the squash that's NOT on the rack) and set aside.
PORK TENDERLOIN: My husband is usually pretty hungry when he works late, so we may finish almost all of a small pork tenderloin ourselves (just 2 people, and I only eat 2-3 slices). So, decide how much you need by how many people and how big their appetites are.
ASPARAGUS: I had bought a bunch of asparagus and used half of it the night before, so half of a smaller bunch was enough for 2 of us. I cut about 1" off the bottoms of the stalks.
ACORN SQUASH: Get enough so that each person has 1/2 squash. They really cut in half easily, if you stick a small sharp knife into them, and then slide it down one side. I turn it over and slide it down the other side, meeting at one (or both) ends. Pull them apart, scoop out the seeds & throw them away.
***
Put the pork tenderloin(s) on the rack. Then put the asparagus on the rack (obviously across the rack, so that it doesn't slide down onto the pan). Spray the asparagus with the butter non-stick spray; and then sprinkle salt & pepper to taste all over it. Spray the cut sides of the Acorn squash with the butter non-stick spray and also sprinkle a little salt & pepper on them too. Put the Acorn squash cut-side DOWN directly on the foil (not on the rack ~ it needs to steam inside while it roasts). And, there you have it!
My tenderloin instructions said to roast for 30-40 minutes per pound. I had 1.27 lbs. and 35 minutes total was absolutely perfect for everything! Let the pork tenderloin rest about 5 minutes before slicing.
SQUASH NOTE: I like to put some real butter in them (and sometimes even a drizzle of maple syrup or honey). If you don't think they're soft enough, turn them cut-side down and put them into about 1/4" water in a microwave-proof pan and zap them in the microwave for about 4-5 minutes. That should get them nice & soft.
