Preheat the oven to 450 degrees. Add the cauliflower, shallot, oil and soy sauce to a bowl. Toss to coat evenly and spread out on a baking sheet. Place in the oven on the lowest rack and roast for 30 minutes, flipping halfway.
While the veggies are roasting, prepare the ramen. Heat the sesame oil in a large pot over medium heat. Add the shallot, garlic and ginger. Cook for 2-3 minutes, stirring frequently. Add the broth, soy sauce, red curry paste, rice vinegar, agave, peanut butter, coconut milk and bell pepper. Bring to a boil and stir until everything is incorporated. Lower heat and simmer for 10-15 minutes.
Add the juice of 1 lime, kale and cilantro. Cook for an additional 5 minutes, or until the kale is wilted. Taste and adjust seasoning as needed - if you want more spice, add some red pepper flakes.
While the broth is finishing, bring a separate pot of water to a boil.** Add the ramen noodles and cook for 2-3 minutes, or until tender, then drain.
To assemble, add ramen noodles to each bowl, ladle broth over the noodles, then top with roasted cauliflower/shallots. Add green onion, cilantro, peanuts and lime wedges to each bowl before serving.
