I'm vegan, but I made a sauce that a good friend once told me was "really, really like Velveeta, only nicer" for pasta and broccoli:
1 large carrot
1 medium sized yellow onion
2 medium-large potatoes
Chop and boil in 1 & 1/2 cups water until tender. Retain water.
1&1/2 cups firm tofu (chopped)
2/3 cup nutritional yeast (this may have another name in the UK, but I never used it before emigrating, so I'm not sure; scroll down to
see what it looks like)
2 tbsp lemon juice
2 tsp salt
1/2 tsp garlic granules
Blend all ingredients until smooth.
It takes 20 minutes tops to put together (I use a food processor or immersion blender) and I keep being told by omnivores that it's really good.
