Prepare keto buns as instructed and let fully cool. I make mine the night before, but it is not necessary.
Preheat oven to375 degrees F.
Break buns into 1 inch chunks and place on baking sheet.
Drizzle buns with butter and 1 teaspoon Italian Seasoning.
Bake for 15 minutes, remove from oven and set aside.
Decrease oven temperature to 350 degrees F.
Heat 2 tablespoons olive oil over medium-high heat.
Add minced garlic, 2 tablespoons Italian seasoning, salt, and pepper to the pan and mix well.
Finally, add onion, celery, and carrots to pan and saute until desired tenderness. I sauteed them for about 10 minutes.
Once the veggies are nicely cooked, add vegetable broth and let heat for 1-2 minutes.
Add bread and vegetable mix to a casserole dish and make sure it is well mixed such that the bread is coated with liquid.
Bake for 15 minutes covered.
Remove cover, stir, and bake for 15 more minutes.
Stir again and serve warm.
