Preheat oven to 400 degrees F (convect/fan). Add tomatoes to a baking dish with 1/4 tsp each kosher salt and pepper, and 2 tsp olive oil. Toss, roast 20 to 25 min until skins are wilting and juices are releasing.
Meanwhile, boil water for pasta and cook the pasta in salted water until al dente according to package directions, then drain.
While those are cooking, add shallot to a large pan on medium heat, with the 2 tbsp olive oil and 1/2 tsp each kosher salt and pepper. Stir, cook for 3 to 5 min until softened and starting to brown. Add minced garlic, cook another min.
Add broccoli florets and vegetable broth, cover and cook for 2 to 3 min until fork tender then add sun-dried tomatoes, cooked pasta, the roasted tomatoes with their juices, and herbs. Gently stir, add in optional lemon juice to taste, and top with toasted pine nuts. Other great toppings are red chili flakes and vegan parmesan, optional.
