Medium dice the potatoes. Place on the sheet pan.
Drizzle with olive oil and season with salt, pepper, and half the spice blend (you will have extra).
Toss to coat; arrange in an even layer.
Roast 18 to 22 minutes, or until browned and tender when pierced with a fork. Remove from the oven.
Prepare the remaining ingredients
Transfer to a large bowl; cover with foil to keep warm. Rinse and wipe out the pan.
Meanwhile, halve, peel, and thinly slice the onion.
Peel and roughly chop 2 cloves of garlic.
Roughly chop the parsley leaves and stems.
Cook the vegetables
In a medium pan (nonstick, if you have one), heat 2 teaspoons of olive oil on medium-high until hot.
Add the sliced onion; season with salt and pepper.
Cook, stirring occasionally, 3 to 4 minutes, or until lightly browned.
Add the sliced pepper. Cook, stirring occasionally, 3 to 4 minutes, or until slightly softened.
Cut off and discard the stem of the pepper. Quarter lengthwise; remove the ribs and seeds, then thinly slice crosswise.
