Roasted Cherry Tomato and Orzo Pasta Bake

This one-dish healthy pasta bake is the kind of cozy, flavor-packed dish you’ll crave on repeat. Juicy cherry tomatoes are roasted until they burst and caramelize, creating a naturally sweet, jammy sauce that clings to the tender orzo. Artichoke hearts, chickpeas and baby spinach bring fiber, protein and plenty of flavor, while a sprinkle of fresh mint and two kinds of melty cheese tie everything together into one bubbly, golden-topped bake.

Slow-Roasted Pork and Mushroom Strata

We like to include a strata in our weeknight meal lineup because it’s the perfect vessel for pre-cooked proteins and vegetables – just whisk up the custardy base, fold in your bread and then throw it in the oven when you’re ready to eat! We love the combination of creamy fontina, roasted mushrooms and fork-tender pork (start by making a batch of Meal-Prep Roasted Mushrooms and Meal-Prep Slow Roasted Pork for ease).
