Chop the avocados and place in a bowl with the mint, salt (if using, but feta is salty), pepper, lime or lemon juice and Jalapeno sauce (if using).
Just blend with a fork and add crumbled feta. Pile onto toasted muffins and drizzle lightly with olive oil, a little more black pepper and top with herbs for garnish. Try a light sprinkle of Nanami Togarashi for an extra kick.
Serve with the tomatoes and spring onion mixed together with a kiss of olive oil.
