Not only is this vegetable spread versatile in an omelet, on a pizza, or the perfect appetizer topping, so it the buttery Aged Havarti cheese.
By Natalie McLaury

I’m one of those people who has no problem eating the same food over and over again. So long as it’s something I like, I’m totally down with leftovers…two, three, even four days in a row! I get that not everyone is that way, however, but I’m going to offer you the best of both worlds today. I’m obsessed with this roasted vegetable puree. It’s easy to make (especially if you have a food processor), makes a huge batch, and is healthy to boot!
The spread has proven as versatile as I had hoped. It’s excellent inside an omelet, divine as a pizza crust, and as you see here, the perfect topping for crostini. Appetizers don’t get much easier than this. Slice and toast bread, top bread with the roasted veggie spread and cheese, and bake until warm and melted.
I stuck with Castello’s Aged Havarti, which is quickly becoming one of my favorite cheese. Much like the roasted vegetable spread its paired with here, havarti is totally multifunctional. I’ve broken away from always using mozzarella on pizza and find the buttery havarti adds a unique flavor element. I love what the cheese does when pressed inside two pieces of bread in my panini press. Of course it goes without saying that I don’t mind it sliced and eaten with crackers, salami, and wine!

Whip up some vegetable spread, pick up some havarti, and let creativity fly free!

Notes
The vegetable spread can be made ahead and stored in the refrigerator for up to 3 days. Try using the spread in omelets or on pizza for a different twist. If you don’t have Aged Havarti, substitute with another semi-soft cheese like Gouda or Fontina.
