I cannot get enough of summer’s bright and vibrant colors! From the fuschia flowers blooming outside the office where I type, to my breezy teal skirt dusting the floor, and the colorful ingredients I cook with… I tell ya, I’m a winter girl at heart who’s really learning to love this whole summer thing.

I mean, except for the mosquitoes and the sweat, of course. But a little bug spray and a splash in the closest pool/pond/lake can cure all that ails you from June to early fall!

Just look at this mouthwatering medley of vibrant summer veggies! Ratatouille is one of my favorite excuses to use ‘em up and make ‘em shine. Pile your veggies in a big, pretty dish with tomato sauce for a fabulous full-sized side (my hubby’s favorite). Or, grill up those gorgeous squash, peppers, tomatoes and onions to toss them with pasta.

If you’re looking for a gorgeous two-bite treat to serve at BBQs alongside the savory fare, though, I’ve got ya covered.

But what’s a good crostini without cheese?

Let’s do it like the French and grab the best baguette we can find, slather it with a bit of butter and toast it ‘til golden brown. Sprinkle on a pinch of shredded mozzarella, slip it back into your oven, and when it’s ready, ravish it with warm, melt-in-your-mouth roasted ratatouille!

You can serve these beautiful bites hotter than a Texas summer, or at room temperature if timing is tricky. If you take it from me, the toastier the tastier. When those veggies have a little heat underneath them, you can really taste their salty, earthy flavors. Combined with the gooey mozzarella? Oh, don’t even get me started.

Sprinkle the crostini with parsley, pop ‘em on a tray and pass these out to party guests for any summer occasion. And, don’t forget to grab yourself a glass of crisp white wine for all your hard work! Even though they were a piece a’ cake…

  • 3 cloves garlic, minced
  • 2 tsp. Italian seasoning

I don’t know how people like winter and not summer (NOT a winter girl- except for soup making). When I was growing up, my parents had a pool and that’s pretty much where I spent my summers. Hoping to get my little girl hooked on her kiddie pool soon :)
