1 small yellow onion
1/2 medium red bell pepper
1 cup California walnut halves (4 ounces)
1/2 head cauliflower (about 1 pound)
1 teaspoon olive oil
1 teaspoon ground mustard
1/2 teaspoon garlic powder
1/4 teaspoon kosher salt
1 (8-ounce) can tomato sauce*
1/4 cup ketchup
2 tablespoons packed dark or light brown sugar
1 teaspoon Worcestershire sauce
4 hamburger buns
12 dill pickle slices
Finely chop 1 small onion and 1/2 medium red bell pepper, and place together in a bowl. Finely chop 1 cup walnut halves. Coarsely chop 1/2 head cauliflower (about 1 pound) until it resembles cooked and crumbled ground beef, but not so fine as riced cauliflower.
Heat 1 teaspoon vegetable oil in a Dutch oven or large, heavy-bottomed pot over medium-high heat until shimmering. Add the onion and bell pepper and cook until soft and beginning to brown, 4 to 5 minutes. Add the cauliflower and cook until tender, 4 to 5 minutes. Stir in 1 teaspoon ground mustard, 1/2 teaspoon garlic powder, 1/2 teaspoon kosher salt, 1 can tomato sauce, 1/4 cup ketchup, 2 tablespoons packed brown sugar, 1 teaspoon Worcestershire sauce, and the walnuts. Cook until the sauce is slightly thickened and bubbling, 4 to 6 minutes.
Divide the sloppy joes between 4 hamburger buns and top each sandwich with 3 dill pickle slices.
* you can use 15 ounces of tomato sauce. I didn't want mine real sloppy.
This is FABULOUS! Will be making it again soon.
