We keep getting some or the other squash from our weekly farm delivery. I have this one squash, which I don’t even what it is ..:) It is dirty green with some rough bumps on it, shaped somewhat like a pumpkin.. can anyone give me a name to put on that squash?
I don’t know how you all roast a humongous squash when the squash cutting person (read husband) is not around. The other day I was done trying to cut it open. So I just took the whole Butternut squash, made a couple of tiny knife holes in it, lightly coated it with oil, put it on a baking sheet and popped it into the oven at 335 degrees F and baked it till my knife went in super easy(at least half an hour). Done!
I cooled the squash, cut it open, which was now super easy because it was cooked and soft. Scooped out the innards and cut off the stem. The peel was already separating from the squash so pulled it off.
Chopped it up and refrigerated it.

Ha! I am not playing around with any of those slippery squashes again. I might end up cutting my finger or something. I am going to roast them all whole!
I keep running out of ideas to use them up. After adding the roasted squash to salads, curries, and eating as a side( I still had some left), I decided to put some in an easy sandwich. Load it up with some caramelized onions, drench it all in spicy mayo(Sriracha mayo idea borrowed from Erin’s Reuben twist), and eat it messily.

Steps:
Prep the buns/rolls. Toast lightly if needed. Top the bottom of the roll with lettuce(or baby greens), tomatoes (optional).
Toss the roasted butternut cubes in salt, pepper and herbs of choice. I used parsley.

    Make it easy to cut squash by putting in oven at 350 for 15-20 min and then cool a bit & cut. This cooks and softens the tough rind & even I can cut it.
