Hey there welcome 🙂 I’d say why wait? Start sooner and you won’t look back!
I’m not a vegetarian but we do have a few here that will be happy to help, in the meantime I have an almond milk shake almost every morning for breakfast which is suitable for you, I use almond milk because it is lower calorie and I prefer the taste. I put 1/2 cup of fruit in the blender (raspberries or strawberries or blueberries usually, or a mix) a dollop of full fat greek yoghurt, 1.5 cups of almond milk, 1 tsp vanilla extract, blitz it, drink it… sometimes I leave out the yoghurt, sometimes I add ice. It has become my morning thing. If I really want a treat I add 1/4 of a banana. I know how to live ya know.
Eggs are very versatile I love having a couple boiled and mashed up with salt and pepper just as it is, but often make a big fritatta type thing with eggs and courgette, onion, pepper and cheese. I add bacon but you can leave that out.
Instead of rice, many of us enjoy cauliflower rice – it’s not quite like eating rice but it is ok if you’re having it with something saucy, courgetti is lovely as a pasta alternative – I like mine fried up a little in olive oil with garlic and chilli.
Tonight with my dinner I tried butterbean mash – suggested by someone here in the recipes. I just cooked them and mashed them with a bit of cheese and salt and pepper – it was the closest thing to potato mash I’ve come across and I will definitely have it again.
