Boil, steam or microwave sweet potato until almost tender. Drain.
Heat oil in a medium ovenproof non-stick frying pan over a medium heat. Add sweet potato. Cook, stirring occasionally, until lightly browned and tender.
Add garlic, curry powder and chickpeas. Cook, stirring for a further 1 minute, until fragrant. Stir in peas and chutney until combined. Add spinach. Cook, stirring, until just wilted.
Preheat an oven grill to medium-high. Crack eggs over sweet potato mixture. Sprinkle with feta. Place frying pan under grill. Cook for about 2 minutes or until egg white is set but yolk is still soft. Sprinkle with tomatoes. Serve with lemon wedges.
