Chop courgettes, bell pepper, tomatoes, loads of onion, garlic, mushrooms, whatever you find. Combine with a mixture of thyme, basil and oregano. Finish with pepper and salt. No proteins? Chop 150 grams of tempeh in small cubes. Grill in a drizzle of olive oil. Add the tempeh, a small can of red kidney beans. Serve with boiled pasta. Life can be simple and practical and healthy;-). I love an empty fridge =ready for new material!
