Flaky Vegetable Squares

I bet you thought I’d forgot about this. I didn’t. See, funny things happen when you try to shoot photos for a blog. The colors don’t always come out right. Or a bug appears in the middle of your plate. Or, as with me, you’re just not happy. Not with the pictures, not with the recipe. So, you start over. You work on the recipe. Fix it three times in two weeks. Oh, how my family suffers for my art. They have to eat all the mistakes and practice recipes. They suffer, I tell you!

Assemble all your ingredients.

Or most of them. I always seem to forget something.

Chop up the cauliflower. Count out 20 florets and set aside in a small bowl. Not 19 or 21 florets, 20!

20 cauliflower florets

Put the rest of the cauliflower into a large bowl. Clean and slice the leek. You’ll need 5, one inch slices. Put those in the large, cauliflower bowl. Drizzle them with olive oil, some salt and pepper and give a toss. Spread them out on a large baking sheet.

Ready to roast

Now, cut the tops off of the garlic heads, place on foil square, and drizzle with 1/2 tsp oil.

Wrap the foil around the garlic. Put the garlic on the pan with the cauliflower and roast in a 425º oven for 30 – 45 minutes. Flip them all over at the halfway mark, so they get nice and browned on both sides. Don’t flip the garlic. All the oil will spill out and you don’t want that to happen. After the leeks and cauliflower are browned and tender, remove the pan from the oven and set it aside to cool.

Open the foil around the garlic so it can cool some, too.

I turn my oven off after I pull the pan out. It takes another 20 minutes of preparation before you’ll be ready for it again, so if you want to keep it on or turn it off, it’s up to you. While the garlic is still warm, squeeze garlic pulp from each clove into a food processor.

Add cauliflower mixture and 1 tsp Tamari soy sauce, and puree until smooth. Season with salt and pepper, if desired. Set the puree aside.

You can do all this part ahead of time and put the puree in the fridge until you are really to continue with the dish. Just pull it out, so it can come to room temperature while you are working on the rest of the recipe. This would be a great time to get the puff pastry out of the refrigerator, too.

Chop the head of broccoli into florets. Halve the carrot lengthwise, then cut into half moons. Take the remaining leek part, cut in half lengthwise, and then into 1/4 inch strips. Pile all this into a bowl and dump in the mushrooms.


ready to sautee

Place a large fry pan on the stove over medium high heat. Swirl in the oil and dump in the mixed vegetables and stir fry. While they are cooking, combine the wine, cornstarch, Tamari soy sauce, thyme, salt, & pepper, in small bowl and stir until cornstarch has dissolved.

Now, unfold the puff pastry on a work surface. Roll it flat into a 12 inch square. Cut the square into 4 smaller squares and put on a lined baking sheet. Chill the dough for 15 minutes to get ready for the next step. Heat your oven to 425º.

various filling stages

puree, then vegetables, then pepper strips

Spread 1/4 cup of the cauliflower puree in the center of each pastry. Top the puree with a scoop of the vegetable mix. Arrange 2 red pepper strips on each pastry, laying one strip from top to bottom and the other from side to side.
