Grilled Watermelon & Halloumi Salad

Meatless Monday has a nice ring to it, but meatless Fridays make a lot more sense to us — use up all your perishable proteins early on in the week and then eat vegetarian to finish up the produce you have left. Halloumi is a semi-hard cheese that stands up to heat without melting, making it the perfect meatless protein to make on the grill. Make the vinaigrette on Sunday, and prep the salad the day of.
