Za'atar Pasta – La Boîte

Ingredients

• 1 pound bite-sized pasta, I used a rustic orecchiette since it takes about the right amount of time to cook
• Salt
• Olive oil
• 1 large onion, peeled and chopped
• 1 Tbsp Za'atar, plus more for garnish
• 1/2 pound sausage, sliced (optional)
• 1 cup chopped cauliflower stem or kohlrabi (optional)
• 6-8 small and tender assorted summer squash, cut into half moons
• 2 sweet peppers, seeded and cut into thin strips
