Prep the ingredients. Cut the carrots into thin circles. Drain and rinse the great northern beans.
Cook the veggies. In a large skillet over medium-low heat, heat 1/4 cup of water. Add the carrots and broccoli. Simmer for 3 to 4 minutes, stirring occasionally, adding an additional tablespoon of water if the pan gets dry.
Combine the flavors. Stir in the great northern beans, coconut milk, red curry paste, and salt. In a small mixing bowl, whisk the cornstarch with the remaining 2 teaspoons of water, then add this slurry to the skillet. Increase the heat to high and cook until the sauce begins to boil. Reduce the heat to low and simmer for about 5 minutes, or until the sauce thickens and the veggies are tender.
Prepare the cauliflower rice and serve. While the curry simmers, cook the cauliflower rice according to the package instructions. (Some brands differ, but many are in microwavable bags and only take a couple minutes to cook). Divide the rice among 4 bowls and top with the curry.
