For the salsa: place all ingredients except for the cilantro and lime on a baking sheet, and broil for 8-10 minutes, until the tomatoes start to look charred. Throw broiled vegetables in the blender with cilantro and lime juice, and blend until smooth. Add salt to taste.
For the guacamole: mash all ingredients until combined, and chunky.
For the sweet potatoes: place sweet potato fries and broccoli florets on a parchment lined baking sheet, and drizzle with olive oil and sprinkle with salt. Bake until tender, about 30-40 minutes.
To assemble: Place sweet potatoes on a serving platter, and add broccoli on top. Top with salsa, guacamole and feta. Serve immediately.
