Sounds like that telly programme when they were given a few ingredients to make a meal, Wilma. I think about a teaspoon of lemon juice and mash the avocado with salt and pepper.
Have you tried roasting garlic? If you roast it in the oven until brown and sqeeze out the flesh, it is much gentler. Otherwise I need a side order of Gaviscon. 
To keep the menu ideas coming; we had a mixed vegetable tagine (carrot, squash, onion, garlic, tomatoes, aubergine, courgette and green beans, with cumin, raz-al-hanout, cayenne and saffron), served with yoghurt last night. Tonight is an OH special of fish, spinach and cream. Lunch today was cheese (Lidl's Italian week cheeses) tomato and cucumber with a couple of chickpea flour crackers and Friday was egg mayo salad.
