1 each green and golden zucchini, cut into 1/2-inch dice
1 cup low-sodium chicken broth
2 tbsp unsalted tomato paste
2 tsp reduced-sodium soy sauce
6 whole-wheat hamburger buns, split
4 1/2 tsp arrowroot, dissolved in 2 tbsp cold water
Sea salt, to taste
1/2 cup shredded Parmesan cheese
In a large skillet on medium-high, add beef and cook, breaking up with a spatula or spoon, for 1 minute. Add butternut squash and cook, stirring occasionally, for 2 minutes. Add onion and cook, stirring occasionally, until beef is browned and onion is becoming translucent, about 3 minutes. Add garlic and cook, stirring occasionally, for 1 minute. Add tomatoes, zucchini, broth, tomato paste and soy sauce, increase heat to high and bring to a boil. Reduce to a simmer, cover and cook until vegetables are tender and mixture is saucy, about 20 minutes.
Meanwhile, arrange a rack 3 to 4 inches from top heat source and preheat broiler to high. Arrange buns, cut side up, on a baking sheet. Toast until lightly browned, 2 to 3 minutes.
Add arrowroot mixture to beef mixture, stirring until sauce thickens, 30 seconds to 1 minute. Season with salt.
Arrange buns on plates and top with beef mixture. Sprinkle with cheese.
This enchilada-inspired casserole has a mild heat that's balanced by cooling yogurt. If you already have cooked chicken on hand, you can skip the first step - if doing so, you'll only need 2 cups broth.
While it’s not traditional to cook jambalaya in a skillet – it’s typically made in a pot – spreading it out helps it cook more quickly. It also means the top can get sprinkled with panko and finished under the broiler, adding a crunch that complements the hearty mixture.
