To prepare the roasted tomatoes the day before:
Heat the olive oil in a large skillet over medium heat. Add the onion and mushrooms and cook 5 minutes, or until the onion begins to turn translucent.
Add the sun-dried tomatoes and garlic. Stir and cook for another 3 minutes, or until fragrant.
Add the white beans, fire-roasted tomatoes, balsamic vinegar, honey, oregano, thyme, salt, and pepper. Stir to combine. Cover and reduce the heat to low. Cook for 10 minutes, stirring occasionally, until warmed through and well-combined.
Garnish with fresh basil.
