Notes/Tips:

  • You can roast the vegetables from before and keep them.

  • If you want to use homemade pesto click here for the recipe.

  • Use savory slider buns. Sweet buns can make this recipe too sweet. I used Kings Hawaiian Savory rolls for this recipe.

  • You can use two different kinds of cheeses. I like the combination of mozzarella and pepperjack but you can use any you like.

  • Do NOT forget to poke the holes in the slider buns.

  • Covering with foil is a must.

  • If you can’t find everything but bagel seasoning in stores, here’s a recipe to make it at home.
