Step one
Preheat oven to 425 Fahrenheit. While oven is heating, toss cauliflower florets with oil and salt and pepper in a large bowl. Transfer florets to a baking sheet. Roast for about 35-40 minutes, moving the florets around occasionally, until they are nicely browned but not limp.
Step two
Toast your hot dog buns. Slather the inside of the buns with hummus and place your hot dawgs inside the buns. Nestle in your roasted cauliflower. Spoon tomato achaar across the bun and top with hot mix.
