Once the roasted garlic has cooled, separate the cloves and squeeze to extract garlic pulp. Discard skins. Set aside.
Heat olive oil in a large saucepan over medium-low heat. Add the shallot and crushed red pepper flakes, and cook, stirring often, for 1 minute.
Add the quinoa to the saucepan and cook, stirring often, for 2 minutes.
Add the broth, then season with sea salt and freshly cracked pepper to taste. Bring to a boil, then cover with a lid and reduce the heat to a simmer for 15 minutes, or until liquid is absorbed.
Remove from heat; stir in garlic pulp, spinach, tomato, and toasted pine nuts.
Pour into a serving bowl and top with shaved Parmesan. Serve immediately. Enjoy.
