Shrimp Arrabbiata With Zucchini 'Spaghetti'

Ingredients

• 2 medium green zucchinis (spiralized into noodles or sliced into ribbons)
• 3 tablespoons olive oil

• 1/2 red pepper (capsicum/bell pepper, finely diced)
• 1/2 teaspoon salt (or a little more if you like)
• 1/2 teaspoon chilli flakes or chilli pepper (less if you like it more mild)
• 3 cloves garlic (finely diced)
• 1.5 cups diced tomatoes (or passata sauce)
• 1/4 cup grated parmesan (or aged cheddar (optional), nutritional flakes can be used if you avoid all dairy)
• Freshly chopped parsley or basil for garnish (optional)
