This is one of those simple weeknight veggie sides that ends up on repeat. Sweet red peppers and tender zucchini roast with olive oil and everyday herbs until caramelized and flavorful. It is colorful, nourishing, inexpensive, and flexible enough to serve with whatever protein or grains you already have.

When life is full, I lean on basics like this. Ten minutes of prep. One sheet pan. You get a clean, vibrant side that supports strength, energy, and calm digestion.

I make this for meal prep, quick dinners after school pickup, and those nights when I want to feel good but do not want to think too hard.
