Preheat your broiler and set the oven rack to the highest level so that your veggies are 2-3 inches from the heating element
Peel
deseed
and cut butternut squash I prefer to cut it into about 1/3 matchstick
but dicing works well also
Peel onions
cut in half and then into 1/4-1/3 strips
Scrub carrots and cut into large matchsticks or 1/4 coins
Put the veggies into a large bowl
drizzle with olive oil and toss to coat Sprinkle with all spices and toss again to even distribute spices
Spread veggies in a single layer on a large jelly roll pan You may have to do more than one batch
Broil veggies for 4-5 minutes
or until the first side gets medium brown Stir or flip veggies and put in for another 3-4 mins or until the outsides are crispy and the insides are tender Repeat with any remaining veggies Serve as soon as possible
though I was able to put the first batch in a warmed casserole and keep until the second batch was done without comprimising the texture
