Add garlic, harissa, seasonings, and salt + pepper. Stir and cook for 1 minute, until fragrant. Add crushed tomatoes and fold-in the spinach. Simmer for 10 - 15 minutes, uncovered. The sauce will slightly thicken.
While the sauce simmers, slice and toast the baguette.
When the sauce is ready, make three wells and crack in the eggs. Cover and cook until the eggs are set to your desired consistency. This will take between 4 - 6 minutes.
For maximum flavor, top the entire skillet with recommended garnishes and serve immediately with toasted baguette.
