As with many roasted veg recipes, use this idea as a general guideline. Feel free to play with the spice mixture—use regular sweet paprika for the pimentón, or even add a pinch of cayenne if you want a little heat. Cumin, coriander and chili powder would also be fun to play around with! If your oven heats really evenly you can bake two sheet pans at a time on the top and bottom. If your oven is unevenly heated (like mine! :), then bake one sheet pan at a time in the center of the oven.
